Fan and air conditioner hire

There are two options when it comes to the cooling of spaces: fans or air conditioning. Low-noise fans ensure that the space is properly ventilated. They are used in factories, garages and workshops. Air conditioning units actually cool the space and quickly produce a pleasant working environment.

Heater hire

The temperature can fall very low in the Netherlands. With our range of electrical and diesel heaters we can help you make sure that your construction site or indoor event stays nice and warm, so that the temperature is always comfortable. Diesel heaters are suitable for heating workrooms, warehouses and marquees. They are available with output up to 220kw and emit no combustion gases, so the air stays clean and odourless. Electrical heaters with output up to 15kW are better suited to smaller spaces. They produce clean, dry and warm air.

Building dryer hire

Does your work involve drying out spaces? You might want to consider hiring a building dryer. These machines can quickly and efficiently dry out a humid space. They are used on both new-build and renovation projects as well as in response to flood damage.

Calculating heater capacity

So you're looking for a heater, but you don't know how to work out what you need? The type of heater you require will depend on the volume of the space to be heated and the level of insulation. Then all you need to know is the number of degrees by which you need to raise the existing temperature. Below you will find a handy formula to allow you to calculate how many kW per hour you will need to bring the space up to the required temperature.

Suppose you need to heat a space 20 x 15 x 4 metres (1,200 m3). The room is poorly insulated and the current temperature is 10°C. The desired temperature is 20°C. You can use the formula below to determine the required kW:
Volume (m3) x insulation factor x required temperature increase = kcal per hour
Using the figures above this gives: 1,200m³ x 3 x 10 = 36,000 kcal

Convert Kcal to kW:
36,000 / 860 = 41.87 kW per hour

*Insulation factor:
Good insulation: 1
Average insulation: 2
Poor insulation: 3
Virtually no insulation: 4
