Terms and Conditions relating to the installation of Powder Coating Equipment

  1. The site area must be clear and have a level concrete floor.
  2. Access by a 1.5 ton fork lift truck must be possible at all times during installation, including loading and unloading.
  3. A fork lift truck must be available during the building process.
  4. An electrical supply of 3 phase and neutral must be provided and terminate in an isolating switch that is within 3 meters of the installation.
    • Capacity as follows:
    • Ovens up to 6 Mrts = 1 x 3Kw motor
    • Ovens over 6 Mrts = 2 x 3Kw motors
    • Spray booths up to 2 Mrts wide = 1 x 5.5Kw motors
    • Spray booths 3 Mrts wide = 2 x 5.5Kw motors
  5. In the case of Natural Gas a gas supply with a dynamic pressure of 21m. Bar and a flow rate of 20m3 must be available. If propane is supplied from an outside tank, a low pressure regulator must be fitted onto the termination of the pipe run and fitted to the outside wall. This must be suitably sized to supply a dynamic pressure of 32m. Bar. If 47kg bottles are to be used the high pressure and low pressure regulators will be supplied by ourselves but the secure housing of the bottles is the responsibility of the customer. 2 bottles in tandem are suitable for ovens up to 4 Mrts, 4 bottles for sizes greater than 4 Mrts.
    • The gas supply must terminate in an isolating valve that is in an accessible position and can be accessed quickly in the event of an emergency. The valve must be compliance with BB EN T46 and be switched off after every shift.
    • It is the customers responsibility to have the gas supply installed and connected.
  6. Exhaust Flue
    • The exhaust flue is the responsibility of the customer. A 250mm diameter adjustable damper is supplied and attached to a roof panel. The exhaust chimney is required to be attached to this and to terminate outside. It is preferable if the chimney is straight but if a bend is required it should be no more than 45º with a further 45º bend outside to return the outlet to vertical. A cowl must be fitted to the end.
    • All powder coating ovens are direct fired, that results in all products of combustion being recirculated, unlike a boiler for example that has a closed or indirect system. These circumstances require an adequate ventilated system that necessitates a suitable extraction fan. Details of the size requirements can be found in the information booklet provided.
  7. Ventilation
    • It is important to understand that all powder coating and general process ovens are direct fired, not indirect fired as in, for example, a boiler. The removal of fumes therefore relies on good ventilation rather than bleeding a portion of the hot ait to atmosphere. General fumes are vented via an exhaust spigot attached to the oven. It is important that a wall or roof fan is fitted of a suitable size. Advise can be given, but it is the customer’s responsibility to ensure suitable ventilation is supplied and fitted in the area the oven will be installed. An air change of 15/20 times per hour is required.
