Switching from R404A or R507A
Since 2020, new condensing units for R404A and R507A may no longer be placed on the market. As an interim solution, R452A, R448A or R449A are options, depending on the manufacturer's approval; from 2030, new stationary refrigeration systems may only use refrigerants below GWP 150, such as R290.
Refrigerant as stated in the item details; the approval in the manufacturer's data sheet is decisive. Exceptions (e.g. safety requirements at the site) and details: Regulation (EU) 2024/573, Annex IV.

Frequently asked questions about condensing units
What is included in a condensing unit – and what isn’t?
A condensing unit is the part of the refrigeration system that sits outside the cold room: compressor, air-cooled condenser and fan, factory-assembled on a base frame or in a housing. Depending on the version, receiver, filter drier, sight glass and pressure switch are already included; the item description tells you which. For the complete system you also need an evaporator, an expansion valve, a solenoid valve, a controller from controls and the refrigerant lines. Everything in one unit, evaporator included, is available as a refrigeration set.
Hermetic or semi-hermetic: what is the difference?
A hermetic unit has a welded compressor; if it fails, it is replaced as a whole. Such units serve refrigerated cabinets, cold rooms and commercial refrigeration, e.g. Tecumseh Silensys or Danfoss Optyma. In a semi-hermetic unit the compressor is bolted, so valve plates, bearings and motor can be replaced. These units are built for higher capacities, e.g. Bitzer ECOSTAR, Dorin or Bock. We can also repair semi-hermetic compressors for you.
What do LBP, MBP and HBP mean?
The abbreviations state the application range by evaporating temperature. LBP (low back pressure) stands for low temperature, e.g. freezer rooms at around −18 to −25 °C. MBP stands for medium temperature, e.g. cold rooms at around 0 to +8 °C. HBP stands for higher temperatures, e.g. beverage cooling or air conditioning. Codes such as MHBP or HMBP cover two ranges. The operating limits in the data sheet are decisive. You can filter the hermetic units by application in the quick selection above.
How do I find the right capacity for my cold room?
What counts is the cooling load: room size, temperature, insulation, how often the door is opened and how much warm product goes in. The cooling load calculator determines the capacity you need; in the cold room configurator you plan room, condensing unit and evaporator together. Then compare the unit’s cooling capacity at your evaporating temperature and the ambient temperature at the installation site according to the data sheet, not just a single nominal value.
230 V or 400 V: which supply voltage do I need?
Small units are usually available for 230 V single-phase, larger ones often only for 400 V three-phase. Check what is available at the installation site before ordering; the voltage is stated in the item name and the data sheet. You can filter the hermetic units by supply voltage in the quick selection above.
Where do I find the model designation of my unit?
On the type plate on the base frame, the housing or the compressor. For Tecumseh it reads, for example, CAJN4492YHR or SILAJ4519ZFZ, for Danfoss Optyma e.g. MCGC015SCA01G, plus an order number such as 114X0449. You can search for both on this page. If the plate is no longer legible, send us a photo of the type plate.
My unit is no longer made. Is there a successor?
Usually yes. For many older units the successor is stated directly in the item name, e.g. ACC CGL45TB1NR, replaced by CGU45TG1NR. Otherwise send us the model via the spare parts enquiry, ideally with a photo of the type plate; we will find a unit with matching capacity, voltage and refrigerant. A successor for an R404A unit is often approved for R452A, R448A or R449A.
Do I have to replace the whole unit if it fails?
Not always. Often the faulty part can be replaced on its own. For Tecumseh units there are fan units, condensers and mounting kits, e.g. for swapping FH/FH2 compressors in Silensys units; for Danfoss Optyma there are EC fan motors. You can find the right compressor via the compressor type search, other fans under motors & fans. If the unit is older and charged with R404A, a new unit is often worthwhile.
May I continue to operate my R404A unit?
Yes, existing systems may continue to run. Since 2020, new units for R404A and R507A may no longer be placed on the market. Since 2020, systems of 40 t CO₂ equivalent or more – around 10 kg of R404A – may no longer be serviced with virgin R404A; reclaimed refrigerant is permitted until the end of 2029. Many units are also approved by the manufacturer for R452A, R448A or R449A, often already stated in the item name. Details are set out in Regulation (EU) 2024/573; you can obtain refrigerant via our refrigerant enquiry.
Which units are available for low-GWP refrigerants?
For A2L refrigerants such as R454C or R455A there are, for example, the Copeland ZXMY, ZXLY and ZXDY; according to the item details, some units from the Optyma Slim Pack and Optyma Plus ranges are also approved for them. For R290 (propane) there are units such as the Danfoss Optyma SC15CNXN0. From 2030, new stationary refrigeration systems may only use refrigerants below GWP 150, with exceptions e.g. for safety reasons at the site. Special rules on installation and charge apply to A2L and R290; your contractor will check them.
Can I install a unit outdoors?
Yes, if it is designed for it. For outdoor installation there are, for example, units from the Tecumseh Silensys range and the Copeland ZXMY, ZXLY and ZXDY; this is stated in the item name or description. For Tecumseh units there are also weather protection housings in sizes S to XL. Make sure air can flow freely through the condenser, otherwise capacity drops.
Who is allowed to connect a condensing unit?
Connecting it to the refrigerant circuit – brazing, leak testing, evacuating and charging – belongs in the hands of a refrigeration contractor; for fluorinated refrigerants such as R404A, R449A or R452A, only certified personnel may do this in the EU. The electrical connection is made by a qualified electrician. Help with your search: find a contractor.
