Cryochiller & Cryopump Repair
for vacuum & high-vacuum systems
When a cryochiller won’t reach temperature or a cryopump won’t hold vacuum, YTI’s cryogenic specialists rebuild the cold head, service the compressor, repair leaks, and recharge refrigerant to get you back to base pressure. Polycold, Telemark, Brooks, Edwards, and MaxCool, repaired on-site nationwide or at our Connecticut depot, with 40+ years of cryogenic experience.
Cryogenic refrigeration is our specialty
Repair for cryochillers, cryopumps, and cold heads
Cryogenic cooling is what holds the vacuum and temperature your coating process depends on, so when it drifts, everything downstream suffers. YTI diagnoses the actual cause, whether it’s a worn cold head, a failing compressor, a lost refrigerant charge, or contamination, then repairs it and verifies the system reaches temperature and base pressure before we leave.
Cryogenic refrigeration has been a core YTI specialty since 1984. We rebuild cold heads, service helium compressors, repair leaks, and recharge refrigerant for Polycold cryochillers, cryopumps, and the Telemark, Brooks, Edwards, and MaxCool systems that support production coaters and high-vacuum labs. Depot repair turns around fast at our Ashford, Connecticut facility, and our field engineers repair on-site nationwide with emergency response within 48 hours.
Repair restores a specific fault quickly. For a deeper, like-new rebuild, see cryopump refurbishment and cryofreezer refurbishment. If you only need refrigerant restored, see refrigerant recharge service.
Chillers, pumps, cold heads & compressors
Cryogenic systems and components we repair
From the cryochiller that speeds your pump-down to the cryopump that holds deep vacuum, YTI repairs the full cryogenic chain. If your system isn’t listed, send the model and we’ll confirm coverage.
Cryochillers & Cryocoils
Polycold-style water-vapor cryochillers and cryocoils that trap water vapor to speed pump-down and improve film quality, repaired to full cooling capacity.
Cryopumps
High-vacuum capture pumps serviced to reach and hold deep base pressure, including array condition assessment and cold-head service.
Cold-Head Rebuilds
Complete cold-head rebuilds, including displacer, seals, and valve service, to restore refrigeration capacity and cooldown time.
Helium Compressors
Compressor service, adsorber replacement, and helium management to keep the cold head properly fed and running to spec.
Refrigerant Charge & Recovery
Refrigerant leak repair, recovery, and recharge for cryochillers and cryopumps, restoring the charge your cooling performance depends on.
Recharge service →Cryo Controls & Instrumentation
Temperature controllers, gauges, and interlocks calibrated and verified so your readouts and protection systems match reality.

Common cryogenic symptoms
Cryogenic problems we solve
If your cooling used to hold and now doesn’t, the cause is usually upstream of the symptom. These are the cryogenic failures YTI is called in to fix.
Won’t Reach Temperature
Slow or incomplete cooldown traced to the cold head, compressor, refrigerant charge, or contamination.
Won’t Hold Base Pressure
A cryopump that won’t reach or hold vacuum, isolated to array condition, cold-head performance, or regeneration.
Won’t Regenerate / Long Regen
Regeneration failures and extended regen times diagnosed and corrected so the pump recovers on schedule.
Compressor & Helium Faults
High or low helium pressure, compressor alarms, and adsorber issues resolved to keep the cold head fed.
Refrigerant Loss & Leaks
Loss of charge and refrigerant leaks located and repaired, then recharged and verified to spec.
Noise, Vibration & Contamination
Abnormal noise, vibration, and contamination diagnosed before they turn into a hard failure.
From warm to verified cold
How a cryo repair works
Diagnose
Tell us the system and the symptom and remote triage starts the same day. We isolate the fault to the cold head, compressor, charge, or controls before any part is replaced.
Repair
We rebuild the cold head, service the compressor, repair leaks, and recharge refrigerant in our shop or on-site, using proven cryogenic procedures.
Test & Verify
The system is run to confirm it reaches temperature and base pressure and holds them, so it’s verified working before it goes back into service.
Document & Warranty
Every repair is documented and warrantied, with recommendations to prevent the next failure and extend the life of your cryogenic equipment.
On-site repair is fastest for production-critical systems; depot repair at our Connecticut facility is ideal for full cold-head rebuilds and precision work. We recommend the right path during diagnosis. See full service details →
