cooling units
determining the cooling unit using charts
In order to select the unit best suited to your requirement, the values of three parameters are required: maximum ambient temlperature in the area where the switchboard is installed Te (max), the maximum temperature required in the enclosure Ts (max) and the amount of heat to be removed by the unit (Psyst.). Use the selection chart related to the reference temperature Ts which is closest to the required value. Read the Te value on the horizontal axis of the chart and draw a vertical line through this point. The intersections of this straight line and the power curves of the various units give the power that each unit can absorb in these
temperature conditions. Select a cooling unit with a power rating
immediately above the the Psyst. value to be removed.

Avoid any downtime, with the most affordable, reliable, and easiest to install thermal protection product available for electrical enclosures!
Just as quiet as an air conditioner (about 62 dBA), the Vortex A/C noise level is 73% less than other conventional, vortex type cabinet coolers. When the thermostatically-controlled Vortex A/C is operating, the decibel level is about the same as normal human conversation!
This next generation, Vortex Cooler features an integral mechanical thermostat to conserve energy and maintain enclosure temperatures within a range of 27° to 32 °C. Requiring only a compressed air supply to operate, the UL listed Vortex A/C quickly installs in a 1,5" knockout hole to keep electrical control panels cool, clean and protected.
When the going gets tough...
Using vortex tube technology, cold air is generated by the Vortex A/C from the compressed air supply and is distributed throughout the enclosure. Since ambient air never enters the cabinet, it's perfect for harsh, dirty environments. In fact, the Vortex A/C features an optional "purge-air" port that, when opened, will provide a constant positive pressure inside the enclosure to purge the cabinet of any contaminated surrounding air. Withstanding extreme temperature conditions, the Vortex A/C will provide reliable cooling operation in environments up to 79° C.

HXi™ Series Heat Exchanger
Our HXi™ Series air-to-air heat exchangers are designed primarily for cooling indoor and outdoor electronic enclosures. They use a double-sided impingement technology to significantly improve heat transfer performance while reducing heat exchanger size. Tests verify that the HXi™ heat exchanger is capable of dissipating twice the heat load of competitive heat exchangers at a comparable size.
Thermacore’s patented design makes the HXi™ Series a low-cost and high-performance alternative to conventional heat exchanger technologies. There are fewer moving parts for greater overall reliability. Standard units are available with 2, 4, 6 or 8 fans. Custom optional features such as alarms and temperature controls are also available. Units are UL recognized and meet Bellcore GR-487-CORE, NEMA 4 and NEMA 12 requirements.

The Peltier effect is a thermoelectric effect, named after the French physicist Jean Peltier. Respectively doped (n-type and p-type) semiconductor materials are used, which are alternately connected in series, each at two junctions. An electric current flowing through that system causes a change in the energy level of charge carriers, thus providing heat being absorbed at one junction and being evolved at the other.

Heaters
Compact heaters to keeping at a moderate temperature of cabinets and housings with electrical electronic installations.
In switchgear cabinets condensation with variations in temperature, which can lead to malfunctions or to losses of the components in the switchgear cabinet, forms. Heaters prevent subnormal temperatures and work against the emergence of condensation. Heater blowers provide additionally for the even distribution of warm interior air. The heaters are appropriate for continuous operation.
|
|
-Pressure clamp connectors
-Dynamic heating up
-Wide voltage range
-Temperature limiting
-Energy saving
-Clip fixing
-Quick installation
These heaters are used in enclosures where damage from condensation must be prevented, or where the temperature may not fall below a minimum value.
The aluminium profile heater body design has a chimney effect and distributes the heat evenly.
The pressure clamp connectors save time and simplify installation.

Low surface temperature
Quick mounting due to clip fixing
Double insulated (plastic)
Wide voltage range
Small size
Compact heater for the use in enclosures with electrical/electronical components. The design of the heater supports the natural convection which results in a high air-current of warm air.
The surface temperatures on the accessible side surfaces of the housing are kept down as a result of the heater design.
Our complete range of thermostats and hygrostats can directly be connected to the heater CS 060.
This heater is also available in a version with plug-in thermostat requiring no additional wiring (CSF 060).
Both versions are designed for permanent operation.
