Static evaporators: which model fits?
Static evaporators work without a fan. In the shop they are listed by number of tubes and size; their capacity depends on the room temperature and the temperature difference. Tell us the room, temperature and installation location, and we will suggest suitable models.

Frequently asked questions about evaporators and condensers
Which evaporator matches my condensing unit?
Both must deliver the same cooling capacity at the same evaporating temperature. An evaporator’s capacity applies to a temperature difference, i.e. the gap between room and evaporating temperature, e.g. “dT 10 K = 4500 W” for the LU-VE F35HC59N6. The smaller this gap, the less the product dries out and the larger the evaporator has to be. The cooling load calculator determines the capacity you need; you can plan room, condensing unit and evaporator in the cold room configurator, or send us the evaporator questionnaire. Matching condensing units can be found here.
Do I need an evaporator with electric defrost?
For low temperature, yes: below about 0 °C room temperature the evaporator ices up and has to be defrosted regularly, usually electrically via heating elements. You can tell from the suffix in the model, e.g. E for Küba DFBE and LU-VE FHA or ED for ECO EVS. In cold rooms from about +2 °C, off-cycle defrost during compressor pauses is usually sufficient. In freezer rooms the condensate drain also needs heating, e.g. a heating cable.
What does fin spacing mean?
It is the distance between the evaporator fins in millimetres, e.g. “LA=7mm” for Güntner or “7mm” for Kelvion KSC. Narrow fin spacing puts a lot of surface and capacity into a small space and suits medium temperature. In low temperature, frost quickly blocks narrow fins; larger spacing is used there, usually from about 6 mm.
What is a static evaporator?
A static evaporator works without a fan: the cold air sinks by itself. The air hardly moves, unpackaged products dry out less, and it stays quiet. For Rivacold (REC, ESR, SBT, VR and VT) you choose it by number of tubes and dimensions, e.g. 12 tubes, 110 × 140 × 1800 mm. As its capacity depends heavily on room temperature and installation location, the evaporator questionnaire helps with the selection.
Ceiling unit cooler, counter evaporator or high-performance unit cooler?
Ceiling unit coolers such as the Küba DFB are mounted under the ceiling of the cold room; double-flow models such as the ECO DFE distribute the air to two sides. Counter evaporators such as the Rivacold RM 70 or the LU-VE HF are compact for counters, refrigerated tables and cabinets, blowing to one or both sides. For higher capacities there are high-performance unit coolers such as the Küba SG Classic.
What else is needed with the evaporator?
An expansion valve and a solenoid valve in the liquid line, plus a controller from controls. With electric defrost, heating elements in the evaporator and usually a heating cable for the condensate drain are added; you will find both under evaporator accessories, as well as drip trays for counter evaporators.
Where can I get spare parts for my evaporator?
Fan units, fan blades, fan guards and heaters are available under spare parts for Küba and spare parts for Güntner, universal heating cables and drip trays under evaporator accessories, other fans under motors & fans. Have the model designation from the type plate ready or send us a photo of the type plate.
Air-cooled condenser or plate heat exchanger?
An air-cooled condenser releases the heat into the ambient air via fans, e.g. the LU-VE STVF with 90° or 180° valve. A plate heat exchanger or coaxial heat exchanger transfers it to water or brine, for example in water-cooled systems, for heat recovery or in heat pumps. With direct expansion, a plate heat exchanger also works as an evaporator.
What does “capacity at ΔT 15 K” mean for a condenser?
A condenser’s capacity applies to a specific difference between condensing temperature and ambient air, e.g. about 1000 W at ΔT 15 K for the LU-VE STFT 14221. If it is warmer at the installation site, the difference becomes smaller and the capacity drops. So always compare condensers at the same ΔT.
What are the benefits of EC fans?
EC motors have built-in electronics, use less power than simple AC motors and their speed can be controlled. Evaporators such as the ECO EVS are also available with EC fans, and EC fan units are available as replacements for many units, e.g. among the spare parts for Güntner.
My evaporator is no longer available. How do I find a replacement?
Compare the capacity at the same ΔT, the number and diameter of the fans, the dimensions, the fin spacing and the defrost. In our shop these details are usually in the item name, e.g. ECO EVS-101 with 0.84 kW, 580 m³/h and two 200 mm fans. Enter the old model in the search above or send it to us via the spare parts enquiry; we will suggest suitable units.
Who is allowed to connect evaporators and condensers?
Integration into 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. Fans and defrost heaters are connected by a qualified electrician. Help with your search: find a contractor.
