Product Description :
Model KTW 97

Heated by recirculated hot water ranging from 45°C to 70°C

Classification : Zone 2

Range : 200 kg/h subject to conditions in table overleaf.

Operating temperature range : 40°C - 70°C

This safe and reliable hot-water heated LPG vaporizer makes it possible to cover the demands in a medium-sized industrial enterprise where a surplus of hot water or lack of electrical power exists. When installation of a KTW 97 unit is possible and surplus of hot water is available, low installation and running costs will result refer Operational Conditions Table overleaf.

This unit is meant for Zone 2. A minimum distance in accordance with local regulations should be allocated between the tank installation and the vaporizer.

Kosangas LPG recommends that the safety relief valve (gas section) and the drain-off valve of the oil separator (if any) be connected to a pipe to lead any gas from the system out of the hazardous area (vaporizer as well as tank installation).

Easy to install and maintain :

KTW 97 enables quick installation at low cost. It may utilize either a surplus of hot water from a production/heating process or a separate boiler unit. Kosangas LPG recommends installation of a heat exchanger between the heating source and the vaporizer for safety reasons to prevent gas from entering into the water heating source e.g. a boiler. No external control box is needed. Maintenance is minimal and all parts are easy to replace. Kosangas LPG recommends the use of anticorrosion/antifreeze (glycol) solution to provide the necessary protection of the water chamber against corrosion and frost.

Technical Description :

KTW 97 is equipped with the following technical features:

  • Solenoid valve (On/Off) controlled by an electronic thermostat.
  • Temperature sensor protects against liquid penetration and overloading.
  • Two safety relief valves protect the pressure vessels against unacceptable pressure increases both in the GAS and the WATER section.
  • All electrical components are placed inside a compact, tight control box mounted on the side of the vaporizer
  • Colour : RAL 50-05
