Service & Maintenance

When purchasing equipment it is advisable to have your equipment thoroughly serviced at regular intervals. This will ensure that you comply with any health and safety issues arising from poorly maintained equipment.


We can offer after sales service and maintenance contracts on equipment supplied and not supplied by us.


Most fixed air conditioning systems offer a 3 to 5 year manufacturer’s warranty, provided that you take out a regular service and maintenance contract.


We suggest that you take out a service and maintenance contract to:

  • Validate the manufacturer’s warranty
  • Limit breakdown of equipment
  • Cleaner cycled air
  • Ensure equipment is working efficiently and economically
  • Lower running costs
  • Extend life of equipment
Every time any hired equipment is returned to our depot, we fully service and pat test prior to the unit going out on-hire again. We are able to provide on-site servicing and maintenance of equipment for long term hires.

Direct Fired Heaters are best suited to areas that require large volumes of warm air such as factories, warehouses and farm buildings. Although some insurance companies will not cover their usage due to an unguarded flame being present, and fumes can be a problem in poorly ventilated areas.


Indirect Fired Heaters are a little more sophisticated in their design. They can be sited outside, and via flexible ducting will deliver huge volumes of clean, dry fume free heat. Ideal for marquees, food preparation areas, shops, showrooms and factories.

This depends on a lot of factors such as size of area, number of doors and windows, number of people in the area, aspect of the room and machinery (computers etc). As a rough rule of thumb you will need approximately 130kw of cooling per square metre.
The Split Cooling Systems work in two parts. The internal part contains all of the refrigerant workings to cool the area and disposes of the heat via the external part. Even so, all air conditioning units must have access to the outside.


No, all doors and windows should be kept shut during the drying process. Additionally the temperature of the room should be maintained at 61ºc to enable to machine to work efficiently. Providing air movement with a fan can also help to speed up the drying process.

The only sure way is by checking with a damp meter, however, by checking and emptying the container on a regular basis you should see that the container is filling less and less until you are getting an acceptable level of moisture.
Typically, a small De-humidifier will use 0.5kw per hour, and a large De-humidifier will use approximately 1kw per hour. So it depends on how much you pay for your electricity.
