Fan Heater SW02 Quiet fan heater for connection to water in small buildings

Transcription

1 heat model Heater Quiet fan heater for connection to water in small buildings Application is a compact fan heater with very low sound level designed for water connection. It is ideal for use where fan heaters are traditionally used such as in industrial buildings and warehouses, but also in environments with high demands on low sound levels, for example, stores and assembly halls. Comfort Frico's fan heaters are extremely quiet and quickly provide comfortable heating. The heater fan is equipped with an air director, which has individually adjustable louvres and directs the air as required. Operation and economy Frico's air fan heaters have a long life, providing fast and effective heating at a low cost. The air for can be controlled in three steps, which gives energy efficient put. Product specifications Very low sound level. Mounted using the enclosed bracket on the wall or ceiling. Intended to pump hot water up to +0 C in the standard design, but available for water temperatures up to +30 C in special designs. Supplied with air director with individually adjustable louvres that direct the air on one plane. Three fan speeds. Corrosion proof housing made of hot zincplate and powder enameled steel panels. Colour: RAL 906, NCS 0500 (white). Aluminium louvres. Design The fan heater has a classic clean design in white enamelled sheet steel.

6 regulation AV0/5 JVF0/5 TVV0/5 SD0 SWR0/5, valve set This valve set is suitable when there is need for adjusting the water and shutting it off (for the purpose of maintenance). The supply of heat is controlled by a thermostat. Pipe dimension for SWR0 is DN 0 (¾ ) and for SWR 5, DN 5 ( ). Add a suitable thermostat for controlling SWR0/5, like KRT900 or T(K)0. SWR0/5 consists of the following: AV0/5, stop valve Stops the water supply to SW. Consists of a ball valve which is either open or closed. JVF0/5, adjustment valve To adjust the water to desired. (kv value for JVF0 is 3,5 and kv value for JVF5 7,0). TVV0/5, -way regulation valve Pressure class PN6. Maximum pressure MPa (0Bar). Maximum pressure fall TVV0, 00kPa (Bar). Maximum pressure fall TVV5, 6kPa (0,6Bar). The kv value is adjustable in 3 stages: TVV0: kv,6, kv,5 and kv 3,5 TVV5: kv,5, kv 4,0 and kv 5,5 TVV0/5, valve+ SD0, actuator regulation with heat supply controlled by thermostat, but with the option of adjusting or stopping the water. Pipe dimension for TVV0 DN 0 (¾ ) and for TVV5, DN 5 ( ). Add a suitable thermostat for controlling TVV0/5 + SD0, like KRT900 or T0/TK0. For this type of water regulation the following components are required: TVV0/5, -way regulation valve Pressure class PN6. Maximum pressure MPa (0Bar). Maximum pressure fall TVV0, 00kPa (Bar). Maximum pressure fall TVV5, 6kPa (0,6Bar). The kv value is adjustable in 3 stages: TVV0: kv,6, kv,5 and kv 3,5 TVV5: kv,5, kv 4,0 and kv 5,5 SD0, actuator on/off 30V~ A thermostat controls the actuator to open and close, thereby regulating the supply of heat to SW. The closing time of the valve is 5 seconds, prevents sudden pressure changes in the pipe system. IP40. SD0, actuator on/off 30V~ A thermostat controls the actuator to open and close, thereby regulating the supply of heat to SW. The closing time of the valve is 5 seconds, prevents sudden pressure changes in the pipe system. IP40.
