Flameproof heaters

Grimwood Heating is certified under the IECEx scheme to manufacture flameproof heaters in accordance with IEC standard 60079, which is identical to the Australian and New Zealand Standard for hazardous area electrical equipment.

The product range includes heaters up to 400 kW, using ANSI B16.5 flanges from 15 cm (150 NB) up to 35 cm (350 NB) in classes 150, 300 and 600.

Low-temperature applications can be either carbon steel or stainless steel for marine, food and beverage industries and other corrosive atmospheres. Carbon steel heaters are blasted and finished with a solventborne inorganic zinc silicate coating.

The heaters come with a mandatory, factory set and locked latching relay to prevent overtemperature operation.

A full three-phase thyristor power unit is also available if necessary. These are available with 3-wire star or delta, 4-wire star with neutral and 6-wire open delta load configurations. These units easily interface with plant PLC and SCADA systems.
