CSN® EXPLOSIONPROOF SPACE HEATERS CSN® explosionproof space heaters are used for heating zone 1 and 2 hazardous areas. Standard devices are available in the common temperature classes T1 to T4; temperature classes T5 and T6 can be offered on request. The use of finned tubes for the CSN® explosionproof space heaters is the most economical solution for heat transfer in the field of electric heaters. By coiling corrugated helical fins on tubes of different alloys, we obtain extremely large tubes surfaces and, consequently, low temperatures on their surfaces. We use this interaction to produce explosionproof space heaters on a highquality level. CSN® explosionproof space heaters with coiled fins are intended for horizontal mounting and suitable for both wall and floor mounting (for permanent installation)

the economical alternative Replacement for STRATE 1DF2 and 2DF2 pump controllers suitable for connection to all STRATE fill level recording systems: contact-based or contactless the 2DF2 plus also handles dual level measurement: Sensor/pilot tube and sensor/contactor for outstanding operational reliability the current level and operating hours are always shown on the display

The CCU186 control unit for crawlers possesses a distinct advantage compared to existing products. In fact, all of the performances that are usually achieved with standard control units are now available in the crawler configura­tion. Automatic slow preheating, the progressive rise in voltage with each exposure, as well as a selection of set values are all included in the CCU186. As the CCU186 has been entirely fitted with industrial electronic components, it is perfectly suited to the often extreme conditions of automatic intra-tube control campaigns. GENERATORS All of the generators in the SITEX crawler range are automatically identified and controlled by the CCU186: the interchangeability is total and this can be instantly implemented on-site. Moreover, thanks to a conversion kit, these generators will operate in perfect sync with the SCU286 standard control unit.
