Buy MRI Coldhead in Nigeria.

Where can I buy MRI cold heads in Nigeria?

Start with Franance’s MRI cold head category, which currently lists two part references. The GE HealthCare 46-294100G1-R filtered listing and SHI RDE-412D4 filtered listing isolate the two different brands and exact model identifiers. Open their records for GE 46-294100G1-R and SHI RDE-412D4.

Franance handles these as quotation orders and follows up by phone or email; there is no online checkout. Include the hospital or service-facility destination in Nigeria, the scanner and magnet details, the installed part label, and whether you need a part only or engineering and installation scope. A catalogue listing is an enquiry point, not confirmation of stock, export eligibility, condition, compatibility or a service appointment.

What is an MRI cold head?

A cold head is a component of a cryocooler system associated with the MRI magnet’s cryogenic subsystem. It operates with other parts, such as a compressor and connecting gas lines, and must match the magnet and cryostat arrangement. SHI describes its RDE-412D4 as a two-stage Gifford-McMahon 4K cryocooler; its product page lists cold head, compressor options, helium gas lines, cables and other package components as a configured system. That illustrates why buying a cold head by model name alone is not a system compatibility check.

GE HealthCare identifies 46-294100G1-R as a “Cold Head Assembly, Shield Cooler” and categorizes the item under MRI. That public listing does not publish enough scanner-specific interface detail to identify every MRI model it fits. Do not infer the GE assembly’s exact installation, performance or system compatibility from the label. Obtain the relevant current GE service documentation using the MRI system identity and have an appropriately qualified engineer verify the replacement reference.

The cold head is not the full MRI system, magnet, compressor package, cryostat, helium circuit or service procedure. A parts quotation should say clearly whether it covers a cold head alone or includes other cryocooler components and services. The MRI system remains subject to the OEM procedure and facility controls for any repair or replacement work.

Which MRI cold head models are listed?

Franance currently assigns two product records to spare-parts/imaging-spare-parts/mri-coldhead. GE HealthCare’s 46-294100G1-R listing is specifically titled “COLD HEAD ASSEMBLY, SHIELD COOLER.” GE’s referenced Canadian shop page lists the condition as refurbished. That status belongs to the cited GE listing and does not confirm the condition of a future Franance offer or the part’s test, warranty, export or shipping terms. Confirm the condition and documents for the exact quoted unit in writing.

The second assigned record is SHI Advanced Technologies RDE-412D4, a two-stage 4K Gifford-McMahon cryocooler cold head. SHI’s product documentation lists compressor choices and package options for gas lines, cables, fittings and a tool kit. Some possible package components vary with compressor selection. SHI’s model information describes its cryocooler range and intended system context; it does not establish that an RDE-412D4 matches a particular GE, Philips, Siemens or other MRI installation.

The filtered routes confirm distinct current assignments: GE 46-294100G1-R and SHI RDE-412D4. Review the MRI cold head category for both. The records are not variants of one another and should not be substituted without documented engineering approval.

How do I confirm cold head and cryocooler compatibility?

Ask the MRI OEM or the facility’s qualified MRI service provider to identify the part against the installed configuration. Provide the MRI manufacturer and model, magnet and cryostat identifiers, system serial number, installed cold head and compressor references, and any approved part supersession history. Include the system generation or configuration record when the service team requests it. If the identification plate cannot be read without opening a cover or disturbing the system, do not access it just to prepare a quote; ask authorized service personnel to collect the information.

For SHI RDE-412D4, verify the cold head with the precise compressor model and variant, operating frequency, gas-line connection and length, cable and electrical interfaces, fittings, and the cryostat interface specified by the OEM. SHI publishes supported configurations, but a list of possible compressors is not confirmation that any of them works with your magnet. For GE part 46-294100G1-R, ask GE or the relevant authorized service channel to confirm the exact GE system and part reference; the public shop page supplies no compatibility table.

Require written confirmation of the proposed match before purchase. Ask the reviewing service engineer to identify the source document or system records used, and to state what additional parts, tooling, testing and installation tasks are required. Do not infer equivalent fit from similar dimensions, connector appearance, manufacturer family, nominal stage or temperature, or the word “MRI” in a listing. If the reference or configuration remains unresolved, mark the quote as a technical review request, not as a confirmed replacement.

Is the cold head supplied with the compressor and helium lines?

Not necessarily. Determine the requested scope explicitly: cold head only; cold head plus compressor; or a complete matched assembly with lines, cables, fittings, tools, installation and commissioning. SHI’s RDE-412D4 product page presents a standard scope with a cold head and multiple potential compressor, helium line, cold-head cable, power cable, hose nipple and tool kit choices. The associated footnotes tie different line and cable options to compressor variants. Ask the quote to state the exact included part numbers, quantities and lengths instead of assuming the whole displayed list is included.

For a GE 46-294100G1-R order, confirm whether the quote refers only to the shield cooler cold head assembly or also includes related items, testing, documentation or site work. GE’s public part page names the item and lists a condition, but does not define a complete installation package. List which existing compressor and lines will be reused, then have the MRI service team confirm that decision and any required replacement items.

Keep consumables, accessory kits and service charges separate in the quote. Ask whether the part is new, refurbished, exchanged or repaired; what inspection or test documents accompany it; and which serial or part labels will appear on delivery documents. The category does not establish the supply scope for any specific order.

What installation and service planning is required?

Cold head replacement is MRI cryogenic service work, not an ordinary biomedical spare-part swap. Use current manufacturer service instructions for the exact scanner, magnet and cryocooler. The work plan should be owned by the MRI system service lead and facility engineering team, and performed only by personnel qualified for that equipment and procedure. This guide is procurement guidance; it is not an installation or depressurization procedure.

Before committing, establish the responsible service provider, system status, planned work window, downtime assumptions, required tools and parts, access requirements, acceptance checks, post-work documentation and route back to operational status. Ask who is responsible for any associated cryogen handling, leak or pressure checks, electrical checks, system configuration checks and restart actions, as specified by the approved OEM procedure. Do not attempt to derive these steps from a sales page or generic cryocooler description.

For SHI products, SHI describes medical service and support options, including repair/refurbishment, testing and service arrangements for MRI systems. That does not prove local availability or that a particular service is included in a Franance quote. For GE systems, GE directs customers to its service documentation and service channels; documentation access may depend on system identification and entitlement. Confirm who may access the needed documents, whether work is covered by an existing service agreement, and how any third-party part affects the facility’s contractual obligations.

What information should I send with a Nigeria quote request?

Provide the exact part number and link: GE 46-294100G1-R or SHI RDE-412D4. Include the MRI manufacturer, scanner model, magnet and cryostat details, system serial number, current cold head and compressor labels, and a short description of the failure or planned replacement. Share relevant system records through an approved channel and only to the extent needed for part verification. Do not send patient data, credentials or unrelated confidential records.

State whether you need one cold head or a larger package. For the SHI reference, identify the current compressor and ask the engineer to specify required matching lines, cables, fittings and tools. For the GE reference, ask the service channel to validate the item against the system and state whether the quoted condition and documentation meet the facility’s purchasing criteria. Add the receiving facility, city and state in Nigeria, requested delivery window, quantity and contact for procurement and engineering.

Ask Franance’s written proposal to identify the exact supplied reference, condition, package contents, compatibility evidence, source of any supersession, inspection or refurbishment report, warranty, price and currency, quote validity, availability, export and import assumptions, shipping, duties, lead time, installation and service exclusions. Ask which party is responsible for technical validation and installation. A catalogue match is not an engineering sign-off.

What should I know about condition, supply and warranty?

A cold head may be offered as a new, refurbished, repaired or exchange item, each with different documentation and commercial terms. The GE HealthCare Shop Canada listing for 46-294100G1-R labels that listing refurbished. Confirm whether the proposed part is the same condition and obtain serial or traceability information, inspection records, test scope, warranty and return terms for the specific offer. Do not treat the source page’s status as a promise about a different seller’s inventory.

For SHI RDE-412D4, request the precise OEM part number, offered condition, configuration, origin, and any applicable manufacturer or seller inspection and warranty documents. A manufacturer’s general service statement does not establish that a particular part was rebuilt, that a specific warranty is included, or that the part can be supplied to Nigeria under current terms.

For both, confirm export eligibility, destination acceptance, delivery terms, customs responsibilities, transit handling and insurance, lead time and warranty support for Nigeria. None of these facts can be inferred from the item’s presence in an online catalogue. Ask for written answers before scheduling an MRI service intervention.

How do I request an MRI cold head quote order?

Open the GE 46-294100G1-R filtered listing or SHI RDE-412D4 filtered listing, then submit an MRI cold head quotation request. Include the verified system identity, installed assembly reference, package scope, service plan and Nigerian delivery destination. Franance will follow up by phone or email to clarify the quote order; the site does not take online payment for these listings.

Manufacturer sources and scope limits

The item identity and GE listing condition are based on GE HealthCare’s 46-294100G1-R Shop Canada listing. GE’s service documents information page describes access to equipment manuals and technical service documentation. SHI’s RDE-412D4 product page, two-stage Gifford-McMahon cryocooler overview and medical service information support its model type, system context and published service options.

SHI states that specifications may change and identifies some performance values as reference-only; no installed-system cooling result, helium consumption or service life is projected here. No compatibility, interchangeability, export availability, Nigerian stock, final condition, price, warranty, installation or local service coverage is confirmed. Verify every technical and commercial detail for the offered part and the exact MRI system with the OEM, supplier and qualified service provider before purchase or service work.
