Description
The casing is made of sheet steel, and the impeller has backward-curved blades of strong steel with heat-resistant paint. TCR operates directly in the fire zone, certificate to EN 12101-3 No. 0370-CPR-0384, duties S2 300 °C/2 h and 400 °C/2 h. The class H motor runs on ball bearings, IP55, with a three-phase supply of 230/400 V 50 Hz up to 3 kW and 400/690 V 50 Hz above 3 kW, and in S1 duty the air is from −25 to +120 °C. TCR/R is intended for a location outside the fire zone (certificate 2797 CPR 840443, F400), with a class F motor and a supply of 230/400 V up to 4 kW and 400/690 V above 4 kW. The motor is moved out of the hot stream, so in continuous duty up to +250 °C is allowed, and in emergency duty 300 and 400 °C for 2 h each. CJTCR/R is an extraction unit in a box based on TCR/R, convenient for technical rooms.
How to choose
Sizes range from TCR-1240 to TCR-2271 with 2-pole, 4-pole and 6-pole versions. For example, a TCR/R model at 2900 rpm with a 4 kW motor gives up to 11 110 m³/h. For hot air and gases in industrial processes TCR/R is suitable, while for operation in the fire zone TCR is taken. On request, two-speed motors, belt drive for TCR/R and ATEX certification for all versions are available. The operating point is calculated in the QuickFan program.

FAQ
How does TCR differ from TCR/R?
TCR is designed to work in the fire zone and has a class H motor. TCR/R is installed outside the fire zone, and its class F motor is moved out of the hot stream.
What air temperature is permitted in continuous duty?
For TCR from −25 to +120 °C, for TCR/R up to +250 °C because the motor is moved out of the stream. In emergency duty 300 and 400 °C for 2 h each.
What is the maximum airflow in the TCR series?
About 34 760 m³/h according to the tables. For example, TCR/R at 2900 rpm with a 4 kW motor gives 11 110 m³/h.
Can a belt drive or a two-speed motor be ordered?
Yes, for TCR/R two-speed motors and belt drive are available on request.
What is the power supply of TCR motors?
Three-phase 230/400 V 50 Hz up to 3 kW and 400/690 V 50 Hz above 3 kW, IP55 protection.
