Brochure covers large control/isolation range
Switchtec's new brochure suits those who specify or purchase control and isolation products.
Control panel manufacturers are increasingly under pressure to develop smaller panels, and at the same time to fit more and more heat generating electronic equipment into smaller, confined spaces.
As a result, heat buildup often becomes a problem and manufacturers require methods of efficiently ventilating their control panels.
By fitting a fan into the panel it enables the manufacturer to reduce the size of the panel, as the fan will extract the excess heat.

Switch disconnectors handle more with less
Redesigned and upgraded switch disconnectors from Telergon offer higher current ratings in smaller housings.
However the movement of air through the panel can also cause a problem due to dust and dirt ingress into the enclosure.
Switchtec's range of combined fan filters are able to reduce heat build up in the enclosure while eliminating or at least minimising dust ingress.
To simplify installation, Switchtec offers panel builders a combined low profile fan and filter unit.
Supplied complete and partially assembled, the builder simply cuts the panel (cut out template supplied with fan) to the required size and snaps in the fan/filter combination.
Screw terminals accept the power wiring to the unit.
The combined fan/filter units are weather proof to IP54 as standard, and are UL/CSE approved.
The units are available in AC voltages from 24-230V, and a 24V DC version is also available, as are EMC versions.
Physically, panel cutout sises of 92, 125, 177, 223 and 291mm square are available.
The units offer airflow rates from 23 to 730m3/h.
Switchtec has taken into account the requirements of the panel builders and offers two colours of fan filter combinations, these being grey RAL7032 or grey RAL7035.
Switchtec's stand-alone type axial fans are high quality units with a shielded, ball bearing design that extends the life of the fan.
These are available for AC and DC supplies from 24 to 230V.
AC fans are supplied in black die cast aluminium, and DC fans are supplied as a black glass-fibre-reinforced PBT casting, these fans being self extinguishing to UL94V0.
The fans accommodate an operating temperature of -20 to +70C, and airflow rates from 15 to 300m3/h are available.
Complementary products available in the Switchtec range of thermal control devices are the TRT series of DIN rail mount thermostats, RAC series anticondensation heaters and the CLG series enclosure lighting.
Switchtec's competitively priced range of fans and accessories offer OEMs a complete thermal management system, all available ex-stock.
