We provide field service, in-house rebuild, refrigerant charges, upgrades to new refrigerants and more to all brands of water vapor cryopumps (Polycold, Telemark & MegaCold). Our highly skilled service technicians are either ex-factory service techs or trained by our Service Manager, who has 30+ years of experience in maintaining Polycolds. Our rebuild techniques replicate the original manufacturing as closely as possible by using the same foaming and testing equipment utilized in the initial manufacturing. All repaired and rebuilt units undergo heat load testing to ensure they meet new equipment specifications.
In addition, we can provide completely rebuilt units with a 12 month warranty at 40% off the cost of new. For customers needing a turnkey project, we also supply the refrigerant lines, feedthroughs, cryocoil and installation. Retrofits on existing chambers are usually economical as faster pump down provides more productivity.
Using us instead of the OEM saves you time, money, and aggravation. We provide technical support for all customers during regular business hours. Our Polycold Dashboard allows users to access product information, technical documents and specifications as well as the ability to purchase refrigerant charges, line sets, and spare parts online. The dashboard also provides a convenient location to request field service appointments.

Our Unique Story
Starting in 1999, Schoonover sold water vapor cryo-traps to OEM's & end users. In 2005, Polycold was sold and we lost the product line. But our Experience carried on and we combined forces with a former Service Manager to continue to assist customers in service & support. In our manufacturing facility, we choose to emulate as close as possible to the Original Equipment used on the original build of the unit. Combining our Sales Experience and best in class Customer Support, we have quickly become the predominate service provider of equipment, service and installation. Products wise, we Upgrade Older Units while providing Lower Pricing on all refrigerants (both old & "green gas 02 blends).
High Cost of Poorly Functioning Polycolds
Why Rebuilding a Unit is Cost Effective
- Cost of fully rebuilding a unit is < 40% the cost of new
- Rebuilding a unit will extend the life for many years
- Water vapor in chamber can cause product quality issues
- Ineffective Units cost production time (Longer Pumpdowns)
- Refrigerant Leaks are an environmental issue
- Rebuild process can identify Issues Before They Happen

Product & Service Information
Schoonover provides replacement refrigerant charges for all models, from the P-75 to the PFC 1102HC. The refrigerant charges are a mixture of gases that enable the unit to cool from room temperature to cryogenic temperatures. In addition to full charges, Top Off Charges are also available if the charge is mostly intact in the unit but the lighter gases have been released. Refrigerant Charges ship Fed Ex on a worldwide basis. Please note: some countries do not allow non-Kyoto compliant gases into their countries (such as the EU). In those cases, your Polycold would need to be rebuilt to handle the compliant gases. Therefore, contact us for more information.
Schoonover can provide service and rebuilds of your Polycold units in our California facility. Incoming units are quoted for all consumable parts replacement. Rebuilding includes new foam in the stack and helium leak checking the copper coils. Once the unit is leak checked, the compressor is tested and replaced if necessary. The unit is then outfitted with a new refrigerant charge and fully tested before being boxed up for return. Warranty is 12 months for the parts/work replaced. Our factory is equipped with the same foaming and heat load test equipment as originally used at the manufacturing facility to ensure your unit returns as close to "new" as possible. To set up service, contact us for an RMA (Return Material Authorization) number to note on the shipping documents. Once you have received this number, we will send you shipping instructions.
Do you need additional water vapor cryopumps for your chamber systems? As an alternative to the high cost of new capital, why not consider a rebuilt chiller? We can provide you a fully rebuilt unit with a new compressor covered by a 12 month warranty. In addition, (we) provide a unit that has the Kyoto compliant "green gas" charges. Pricing for the rebuilt unit is approximately 60% the cost of new. Since all rebuilt units have a new compressor, fresh consumables and a new charge, the unit should be ready to run for an extended period of time. Therefore, long-term cost of ownership is comparable to a new unit.
Refrigerant Lines & Spare Parts
Needed accessories for installation include refrigeration lines between the Polycold and the cryo-coil. Just specify the length and if you want Parker or Cajon Fittings. Also, indicate if the connections need to be 3" off-set or even. Spare parts are also available.
Field service repairs are provided on all models. Trained service technicians from our California facility can provide preventative maintenance plans/services and/or field repairs. In addition, priority service for situations where production is down can usually be accommodated.
We design and fabricate cryo-coil designs for all models. Our engineers can take your chamber data and design a coil that fits into that space. This custom coil design provides maximum efficiency for pumping water vapor. Also available is installation of the cryocoil. To get started, provide pictures of the areas in your vacuum chamber system where a cry-coil could be located.
Starting in 2020 for the USA, refrigerant for Polycold units ending in 0 (ex. PFC 1100HC) will not be available due to R-22 no longer being manufactured. These environmental regulations will result in older units needing to be rebuilt in order to meet new Kyoto compliant "green" refrigerant gas requirements. Our shop can handle this upgrade with the cost being approximately 30% of new. This upgrade will make existing units compliant with the new refrigerant regulations and allow tehm to run to specification with the new refrigerants.
