LOB’s WTP-heating system serves as an alternative to the half-tube coil and double-walled jacket. It can be used at excess operating pressures of up to 50 bar and temperatures of 300° Celsius or more. An ideal design in terms of heat engineering is capable of achieving values > 2,400 W/(m2 K) (half-tube coil: 1,600W/(m K).

The WTP (heat exchanging plates) system is a tempering concept which serves as an economical alternative to conventional chemical devices such as the half-tube coil and double-jacket. Compared with these two designs, the WTP- system® offers a large number of advantages:

  • Lower purchase price
  • Lower operational costs
  • Better heat transfer
  • Faster heating
  • Better control characteristics
  • More efficient utilization of the heat transfer medium
  • The performance of existing installations can be raised without the need for additional space
  • Supply lines and pumps can have smaller dimensions
  • Complex geometries are possible
  • All installation positions are possible
  • Lower weight
  • Connectors can be retrofitted easily
  • Clamping plates can be retrofitted
  • Ideal for flat surfaces
