Technical features
- Main applications
Industrial Alfa Genset DCH radiator units are designed for cooling of water or other process fluids for Diesel and Gas Power Generation - DCH Gen-set radiator unit
DCH=standard Cu tube, DCH6= 5/8” Cu tube - Design pressure
10 bar - Fan-motors
3-Phase 400 V-50 Hz squirrel cage induction motors (IEC) are used, on demand 460 V-60 Hz or other power supply - Fan diameters
ø 1250 up to 1440 mm - Fan numbers
1 or 2
Casing
- Casing is made of pre-galvanized sheet steel.
- New frame design provides high rigidity, also for heavy applications.
- Maintenance can be easily done from outside or by entering inside the unit using special inspection doors.
Fan-Motors
- 3-Phase 400 V-50 Hz squirrel cage induction motors (IEC) are used, on demand 460 V-60 Hz or other power supply.
- Protection Class IP55, temperature class F or H, depending to the working conditions.
- On demand greasers can be included.
- Each electric fan motor is wired to a terminal box or a safety switch close to the fan cowl.
- DCH can be supplied with different fan diameters (1250 up to 1440 mm) fitted with fan blades in aluminium (wind profile), fiber glass or galvanized steel.
- Fans can have either fixed or adjustable blades.
- Fans are protected by a epoxy coated or hot deep galvanized metal protection grid.
Options
- Combined version and double circuit (LT/HT)
- Several fin spacings
- Coil treatment for aggressive environments
- Stainless steel tubes
- Counter-flanges
- Vent and drain ball valves
- Extra static pressure drop from 50 to 200 Pa
- Noise absorption
- Expansion tank delivered installed and completely connected to the manifold:
- Basic or with level indicator
- Authomatic venting (optional)
- Over-pressure valve (0.5 bar)
- High temperature piping
- High Temperature Electric Motors
- Electric motor Space Heaters
- Special components for application in hazardous environments (max zone II)
- Electrical parts:

- Terminal box (all fans wired for easy electrical connection switchboard)
Design pressure
- 10 bar
- Each heat exchanger undergoes a pressure and leak test with dry air at 15 bar.
Packing
- DCH radiator units are designed to be installed inside a 40′ HC container.
Coil
- The innovative heat exchanger coil gives excellent heat transfer thanks to new corrugated aluminium fins combined with copper tubing. Tubes and fins are available in different diameters and thicknesses.
- DCH radiators are designed with two vertically positioned, independent heat exchanger coils. Thanks to the two separated coils or the use of split coil circuits it is possible to cool different fluids. This configuration, dedicated to the Power Generation, allows to cool two different circuits (i.e. LT and HT engine circuit) in a unique, compact radiator unit.
- Copper manifolds are provided with aluminium flanged connections, draining and venting nozzles. DCH can have one or two modules, depending on the required performance.
- Each heat exchanger undergoes a pressure and leak test with dry air at 15 bar (design pressure 10 bar).
