In order to optimize the untilization of freezing and air-conditioning equipment, an essential prerequisite is a good and adequate balancing and maintenance.

Many freezing and air-conditioning equipment are maintained much too enfrequently and unappropriately. Optimal operation of freezing and air-conditioning equipment is not only beneficial to users and the environment, but it will, on medium term, be a factor of economy.

Maintenance of room temperature and air humidity depends on the thermal load by personnel, lighting and machinery heat emissions as well as on the influence from the outside.

Control and balancing programs permit the equipment to be switched on and off and balanced as required.
