Ultra-low Temperature Refrigeration Services for Industry – home of Polycold upgrades and Cascade refrigerant gases

Remanufacturing and upgrading your old, under performing system not only extends its life but also improves performance. 60% saving compared to buying new, including comparable warranty.
A comprehensive, 8 step remanufacturing process ensures better than new performance.
Remanufacturing reduces running costs, is environmentally friendly and upgrading brings all Polycold™ and Telemark systems into full compliance with (EU) N 517/2014 F_GAS REGULATIONS
Polycold™ and Telemark systems are critical for of all thin film coating, metallurgical and vacuum heat treatment processes. In collaboration with our partner Druschke our remanufacturing upgrade programme greatly extends the life of PFC00 and 01 series systems and greatly improves the performance and reliability of PFC02 series units.
A Stratox remanufactured and upgraded unit performs better and costs around half the price.
Polycold™ systems are well regarded as tough reliable units. We have designed out sticking valves and blocked capillary lines.
Improved oil handling and high efficiency gas Cascade™ refrigerant blend give you more cooling.
Lower power consumption and low global warming gas and recycling the unit significantly reduce waste.
12 months mechanical warranty when installed by a Stratox channel approved installer.
A remanufactured and upgraded Polycold™ PFC will last longer and perform more efficiently than when it was new. Through a subtle system redesign and Stratox’s advanced Cascade refrigerant (F-Gas compliant), users report faster cool down, lower temperatures, less current draw and no sticking cool valves.
Systems are checked to ensure they are free from leaks.
Critical components, as the condensers are removed, cleaned of scale and oil are retested and replaced.
System heat exchangers are checked for oil contamination, and water ingress into foam, foam is stripped and replaced if required with a new high performance solid vapour barrier installed.
All line components, driers and filters are replaced by better quality, higher capacity alternatives to those originally supplied.
Valves solenoid valves including the cool valve are replaced new for old. The manufacturer and type are identical to Polycold OEM versions.
Hand vales are rebuilt with new internals – every Polycold experiences failures at this point.
Units are upgraded with a new refrigerant discharge arrangement which includes twin high capacity oil separators. This eliminates any compressor oil travelling to the condenser or beyond. This eliminates any possibility of future oil contamination of the stack. Heat transfer is greatly improved increasing efficiency.
The cool valve in particular causes a great number of problems. With all conversions we change the cool valve using a genuine Polycold valve; we also use the OEMs valve service kit for the hand valves in the top of the stack and replace the access port, which is a common leakage point.
Critical components are removed, cleaned of scale and oil, retested and replaced. Price upon inspection.
Included in the cost is replacement of the existing insulated refrigerant transfer lines. We have found these become embrittled in use and prone to leakage. They also have a tendency to be filled with oil from the replaced system which can cause issues with the upgraded system.
Units are tested for function with a Meissner under standardised conditions to verify functionality and performance before despatch. Units are then filled to an over pressure of 10 psi above the Polycold specified maximum to accommodate typical transfer line and Meissner coil volumes.
All F Gas conversions of are supplied with a certificate and label to confirm conversion and compliance. An F-Gas log sheet is also supplied. Refrigerants and oils removed will be disposed of through the approved waste disposal channel certification of which is available upon request.
“As a member of Essilor Group, Isbir Optik demnads high performance and reliability from it’s vendors. We have been very pleased with the service provided by Stratox who supplied us a re-manufactured and upgraded Polycold PFC-1100. The machine has contributed to the smooth running of our plant without any problem for 8 months.”
“On my Site it is all right. I am very glad that you hear about! You can seamlessly use my name as a reference for remanufacturing the old PFC’s. The same for Mr. Druschke. All The remanufactured 12 PFCs running very well. I am satisfied.”
