Cooling & Ventilation
Heating, Drying, Cooling
This Air Cleaner is designed to remove dust and help improve air quality in your working area.
These Ventilator Fans will provide clean air in confined spaces while forcing dirty air out. Also, suitable for welding fume extraction.

The amount of heat required to give comfortable working conditions can be calculated using this step by step guide below: Amount of heat required = Volume in m3 x Temperature rise °C x K x 4 = Btu/hr A Volume (m3) = Multiply Length x Width x Average Height B Temperature Rise (°C) = Subtract the current room temperature from the required temperature C Insulation (k) = Select the description which best describes the area to be heated from the table below. Well insulated Average Badly insulated Hardly any insulation k = 1.2 k = 2.2 k = 3.0 k = 4.0
Calculating the cooling capacity required and the heat load for each room can vary considerably. This depends on the number of lights, the number of people, glass area facing the sun, and the presence of computers and other equipment. Rule of thumb for an approximation of air conditioning loads are: Normal Modern Offices: Portable Buildings: Tents/Marquees: ± 46 W per m3 ± 57 W per m3 ± 95 W per m3
In addition to the type and size of the area to be cooled consideration must be given to any appliances that generate heat in the area. Such appliances are listed below along with the approximate heat emission that they generate. Personal Computer Laser Printer Photocopier Standby Photocopier In Use Fax Machine Coffee Machine TV/ Video Screen ± 150 W ± 500 W ± 200 W ± 1000 W ± 500 W ± 800 W ± 50 W
D Multiply the Volume from A by the Temperature Rise from B. Multiply this by Insulation (k) and then multiply by 4 to give you Btu/hr.
1 kW = 3413 Btu/hr
