CJSX, CJSRX, CJTXR extraction units 400 °C/2 h with belt drive and motor outside the airstream, up to ~38 000 m³/h
Country: · Model: CJSX, CJSRX, CJTXR
The CJSX, CJSRX and CJTXR extraction units with belt drive have the motor outside the airstream, so they handle air up to +120 °C continuously and extract smoke at 400 °C/2 h according to EN 12101-3. The maximum airflow in the tables is about 38 000 m³/h for CJSX and 34 000 m³/h for CJTXR. They are installed outside the fire zone, including in the kitchens of catering establishments.

Description
CJSX has single-inlet suction, a casing of Magnelis steel of category C5 to ISO 12944, an impeller with forward-curved galvanized steel blades, certificate 0370-CPR-0503 and S2 duties at 300 and 400 °C for 2 h each. Sizes range from 12/6 to 30/14, with motors from 0.55 to 18.5 kW. CJSRX and CJTX-C are related, and their transmission is also housed in a Magnelis steel casing. CJTXR is in-line, with a double-inlet self-cleaning impeller with backward-curved blades, an aluminum profile frame, painted sheet panels with 25 mm stone wool insulation, an inspection hatch, a grease tray and a built-in terminal box. It has certificate 2797 CPR 840443, F400, sizes 450–630, and IE3 class motors of 0.75–7.5 kW. The class F motors run on ball bearings, IP55, with a supply of 230/400 V 50 Hz up to 4 kW and 400/690 V 50 Hz above 4 kW.
How to choose
CJTXR with a grease tray is designed for kitchens and restaurants, and it can be complemented with a particle sensor for automatic control, while CJTXR-FE also has an electrostatic filter. For hot air from production areas and technical rooms, CJSX with more powerful motors is taken. On request, a vertical outlet, two-speed motors, left-hand or right-hand drive and special windings for other voltages and frequencies are available.

FAQ
Why is the motor moved out of the airstream?
Because of this the unit handles air up to +120 °C continuously, and in S1 duty from −25 to +120 °C. For this reason it is also used as an ordinary extraction unit for hot air.
What fire resistance do CJSX and CJTXR have?
400 °C/2 h to EN 12101-3, and CJSX also 300 °C/2 h. The CJSX certificate is 0370-CPR-0503, and CJTXR is 2797 CPR 840443 (F400).
What is the maximum airflow of these units?
CJSX up to 38 000 m³/h (sizes 12/6–30/14, 0.55–18.5 kW), CJTXR up to 34 000 m³/h (450–630, 0.75–7.5 kW).
Is CJTXR suitable for kitchens?
Yes, it is designed for the kitchens of catering establishments and has a hatch, a tray for collecting grease and a self-cleaning impeller. CJTXR-FE additionally has an electrostatic filter.
What is the motor power supply?
Three-phase 230/400 V 50 Hz up to 4 kW and 400/690 V 50 Hz above 4 kW, class F, IP55.
