Cooper-k9

Stork Cooperheat’s Cooper-K9 has been developed in response to the demand within the heat treatment industry. Traditional heat treatment modules are heavy and require mobilisation using forklifts and large transport vehicles. The newly launched Cooper-K9 is a mobile and portable 9kVA three output channel heat treatment unit that can be loaded and off loaded from a pick up vehicle without the need for heavy lifting equipment such as a powered fork lift truck or crane.

The Cooper-K9 splits into two halves. The top half contains the six point recorder and three programmer/controllers and contactors. The lower half contains the power transformer and air circulation fan. The compact module not only avoids the use of heavy lifting equipment, in addition it avoids mobilising valuable 50kVA or 70kVA assets to smaller heat treatment work scopes which may require less than 10kVA of power.

To complement and extend the range of compact heat treatment modules, Stork Cooperheat has also developed the Cooper-K9-OPL. This module is lightweight incorporating the power source/contactor unit in three stackable parts. Each part weighs 20kg, which is within the capacity for one person to load and off load from transportation. As with the standard Cooper-K9, the units are simple to stack and then easily transported by means of a pull out (trolley suitcase type) handle and wide roller wheels suitable for use on all typical industrial surfaces. Furthermore, a unit with no inbuilt recorder is available for operators that wish to use their own portable recorders or where chart recording is not required. A six channel unit, using six 30V heaters is also offered with or without an inbuilt recorder.
