Industrial Helical Condensers-CRH Ø 800/910 Range.
SCOPE. Ventilated condensers for industrial use. It consists of a wide range of 162 models in which different types of fans are assembled. This allows us a great variety of solutions and a capacity range of 37 to 1000 Kw and sound levels up to 23 dB(A) (10m).
TECHNICAL SPECIFICATIONS. COIL: It is produced with a 12mm copper tube in staggered arrangement in aluminum fins and high efficiency turbulators. This is supported by copper rings fixed to side plates and separators where the tubes of the coil rest. By this means the coil is floating and thereby avoids any damage produced by dilatation and material fatigues. The coils are subjected to a watertightness test for each unit at 32 bars. These are supplied with Schraderâ valve and charged with inert gas. Alternatively special multi-circuit collectors may be produced.
BODYWORK. It is made of galvanized steel with separate plates so that each fan works over its battery area avoiding interferences among them. These are lacquered in Epoxy polyester coating, polymerized by heat. The condenser is supplied with legs in horizontal assembly. By request they may be installed vertically.
FANS. External rotor with a diameter of 800 and910 mm, 380/415v-50 Hz insulation class F and protection level IP54 according to new norm Erp 2015. These are arranged in 6, 8 and 12 poles permitting a low sound level. In addition, it is available in EC electronical fans that allow an important saving of electricity. At the same time, this regulates easily its revolutions and also controls them. This is connected to a watertight housing of protection level IP54. Optionally, it may be supplied with individual on/off controls.
PERFORMANCES. Condensers performances are tested according to EN327 norm. Room temperature 25ºC, Condensing temperature 40ºC, DT=15K, at sea level with refrigerant R404A.
