Cryochiller Refurbishment
restored to full cooling capacity
When a cryochiller is aging, unreliable, or no longer holds temperature, a full refurbishment brings it back to like-new performance for far less than a replacement. YTI rebuilds the cold head, services the compressor, repairs leaks, and recharges refrigerant, then verifies cooldown and capacity before it ships. Polycold, Telemark, Brooks, Edwards, and MaxCool, rebuilt by cryogenic specialists with 40+ years of experience.
Cryogenic refrigeration is our specialty
Cryochiller rebuilds that restore cooling capacity and reliability
A cryochiller that takes longer to cool down, drifts off temperature, or needs frequent attention is usually past the point where a single repair pays off. A full refurbishment addresses every wear item at once: YTI rebuilds the cold head, services or rebuilds the compressor, replaces worn seals and valves, repairs leaks, and recharges refrigerant, then runs the unit to verify cooldown time, temperature, and capacity before it returns to you.
Cryogenic refrigeration has been a core YTI specialty since 1984. We refurbish Polycold cryochillers and the Telemark, Brooks, Edwards, and MaxCool systems that support production coaters and high-vacuum labs, backed by an in-house machine shop and complete test capability. The result is a unit that performs like new, on a schedule you control, at a fraction of replacement cost.
Need a targeted fix instead of a full rebuild? See cryochiller & cryopump repair. Only need the charge restored? See refrigerant recharge service. Running several units? Ask about our fleet refurbishment rotation program.
Rebuilt from the cold head out
What a YTI cryochiller refurbishment includes
Every refurbishment is a complete restoration, not a spot repair. Here is what goes into a YTI cryochiller rebuild.
Full Teardown & Inspection
Complete disassembly and inspection of the cold head, compressor, valves, and refrigeration circuit to find every worn or failing component.
Cold-Head Rebuild
Displacer, seals, and valve service to restore full refrigeration capacity and the cooldown times the system had when it was new.
Compressor Service & Adsorber
Compressor service or rebuild and adsorber replacement, with helium charge and pressure set correctly to keep the cold head fed.
Refrigerant Recovery & Recharge
Refrigerant recovered, leaks located and repaired, and the system recharged to spec with the correct refrigerant for stable cooling.
Recharge service →New Seals, Valves & Worn Parts
Fresh seals, valves, and any worn components replaced so the refurbished unit is reliable, not just running for the moment.
Performance & Leak Test
Run to verify cooldown time, temperature, and capacity, and leak tested, so the rebuilt cryochiller is proven before it ships.

When to refurbish
Signs your cryochiller needs refurbishment
Cryochillers wear gradually, so performance slips before it fails outright. If you recognize any of these, a refurbishment will usually restore full capacity and reliability.
Degraded Cooling Capacity
The unit no longer holds temperature or reaches the capacity it once did, dragging down your process.
Long Cooldown Times
Cooldown takes far longer than it used to, adding to cycle times and lost production.
Repeated Refrigerant Loss
The system keeps losing charge and needing recharges, a sign of leaks and wear that a rebuild resolves.
Frequent Repairs & Downtime
You are calling for service more and more often, and the downtime is costing more than a rebuild would.
Noise & Vibration
Unusual noise or vibration that points to worn internals heading toward a hard failure.
Aging Unit / Preventive Rebuild
The unit is overdue and you want to rebuild it on your schedule, as a one-off or as part of a fleet rotation.
From worn to like-new
How a cryochiller rebuild works
Evaluate
Send us the unit or its details and we assess condition and scope, then quote the rebuild so you know the cost and timeline up front.
Rebuild
We rebuild the cold head, service the compressor, replace worn seals and valves, repair leaks, and recharge refrigerant to spec.
Test & Verify
The rebuilt unit is run to confirm cooldown time, temperature, and capacity, and leak tested, so it is proven before it ships.
Document & Warranty
Every refurbishment is documented and backed by a warranty, with recommendations to extend the life of the unit.
Cryochiller refurbishment is depot service at our Connecticut facility for a controlled, thorough rebuild. Ask about a spare or rental to keep production running while your unit is in our shop. See full service details →
