ENCLOSURE PANEL SPACE HEATERS & THERMOSTAT MUST FOR EVERY SWITCHGEAR PANEL TO AVOID CONDENSATION

ENCLOSURE PANEL SPACE HEATERS

GIRISHEGO perforrated bodu tubular Space Heaters are ideal for prevention of condensation, corrosion & Leakage currents in L.T. & H.T. Switchgear panel boards , electronic instruments & electric panels etc. The specially developed design incorporates a stainless steel sheathed cartridge (resistance type) heating element in perforated sheet metal enclosure. Blackodized finish ensures rapid heat dissipation.

A 2 x 2.5 mm² porcelain terminal block is provided for electrical connection. Installation can be done in vertical or horizontal position, although horizontal mounting is preferred. Distance from surface of panel should be at least 10 mm. and distance from plastic parts should be at least 50 mm.

Each heater is tested for following specific tests.

1) High Voltage Test At 2Kv for 1min.
2) Insulation Resistance > 10 Mega Ohms.

3) Power rating within ± 5%. 

THERMOSTATS FOR ENCLOSURE SPACE HEATER

GIRISHEGO Thermostats are ideal for regulating the heater at the desired preset temperature, The thermostat knob setting is set such that, temperature inside LT & HT switchgear panels is always above the condensation point, thereby safeguarding any shot circuit, sparking or damage to equipment.

Principle of operation : 

With temp rise, the principle of differential expansion of brass tube and a Nickel/Iron (inver) Rod is used to actuate a highly accurate snap action micro gap switch located in the head which makes it keep the temperature constant within the differential i.e. A single pole, single throw, normally closed circuit breaks (opens) on rise of temperature.

Construction : 

The micro gap switch assembly is mounted on a heat resistant base, with rigid brass pillar terminals. Heavy duty Ag cdo contacts are provided for long trouble free life. A thermosetting cover with clear and precise graduations is provided along with a setting knob. 

Thermostat can be fixed in any position.Two fixing holes of Dia. 5mm are provided at a center distance of 58mm in Thermostat with fixing Bracket model.

These are available in standard stem lengths of 7"(175mm), 11" (275mm). Also Available in 110 V & 415 V.
