Product Description :
Model KTW 97

Heated by recirculated hot water at 75°C

Classification : Zone 2

Range : 700 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
