Heaters for control cabinets RIZUR-OShA-IP20-B with a ventilator (standard version). Designed for use outside of hazardous areas. Heating element - PTC thermistor. The majority of the manufacturers nowadays switch onto PTC thermistors because they not only provide heating but also guaranty safety and long service life.

Heaters for control cabinets (OShA) with a ventilator are designed for setting and maintaining the required temperature range in the control cabinets. It’s important for the protection of the control elements against negative temperatures and moisture to have heating systems in the control cabinets. Heating element used is PTC thermistor.

RIZUR-OShA-IP20-B heaters are manufactured in accordance with the requirements of the regulatory documents developed at the company, that comply with the international standards ISO 9001.

The aluminum body of the heaters designed for the DIN-rail mounting is manufactured in the form of a radiator, with a heating element inside that is protected by an aluminum plate with mounting holes. There’s a special cable canal on the plate created for the convenience of the cable output.

The heater is self-regulating but this system controls only the heater's temperature (saves it from over-heating). In order to control the temperature in the control cabinet, one should use thermoregulators of the ambient temperature (a different device).

It's recommended that the heater should be mounted vertically with space above and below left empty for better convection. The heater is mounted in place with mounting brackets that are in the scope of supply (DIN-rail or screw-type fittings). In case there's a need for temperature maintenance in the set range, then it's best to use temperature limiters (air temperature sensors, thermostats), along with the heater. ("NPO RIZUR" has its own series of this equipment)

There're two types of the RIZUR-OShA-IP20-B connection: terminal connection (standard version) and cable connection. The second one has high-temperature power cables out, the length is specified by the customer.

For installation, the heater can be equipped with screws, M5 bolts, and a bracket for a standard DIN-rail 35 mm.
