Heating Chambers - Heating

Electrically heated cabinets are usually equipped with resistance heating elements which are arranged to the broadest cabinet side. If such an arrangement ist not possible it has to be checked if a two-sided arrangement is useful. For the explosion endangered areas there are explosion-protected resistance heat exchangers
are used. Such heat exchangers are equipped with separate explosion protected controllers. This controller equipment is already pre-adjusted corresponding to
the required temperature class (T2- T 4).

Steam heated cabinets are equipped with ribbed-pipe heat-exchangers which are also arranged to the broadest cabinet side (usually the rear-wall side). The design of heating registers is difficulty in view of desired heating surface, tube cross-section, thickness of ribs to provided as well as material of register and should not be underestimated. Together with the local university we therefore have an EDP-software developed for the design and layout of ribbed-pipe heat exchangers for installation in heating cabinets. So we are capable to calculate the max. possible power output at any operation point (temperature). On the base of your parameters regarding final temperature and the desired capacity of the heating cabinet - inserted in our EDP-program - our heating registers are always optimal sized and designed.

If a layout of a heat exchanger is based only upon experiences it is more than likely that it will be wrong sized. Oversized heating registers will result in a consequence that in the stationary phase (nominal temperature is reached) too high temperature variations can arise. Undersized heating register will result in the consequence that desired final temperature will not be reached or only very slowly.
