Clesse LPG Vaporisers

Clesse is the leading supplier of vaporisers in the United Kingdom and Ireland. With over 50 installations, our solutions have made a profound impact across various industrial sectors. The foundation of our success lies in the expertise and dedication of our exceptional technical and engineering team, who consistently deliver outstanding results. As a result, Clesse vaporisers are widely regarded as the best option in the industry.

Developed and optimised by Clesse, in partnership with Pegoraro, our hot water vaporisers use heat transferred from hot water to Liquid LPG. This creates vaporisation, positive vapour pressure, and velocity to the gas exiting the vaporiser. The vapour then passes through a specially designed conditioning reservoir to separate oil and lower vapour temperature, which protects downstream equipment and appliances. This method of heat transfer has a significant advantage over the directly heated vaporisers available on the market which have tendency to produce excessive amounts of oils.

Features:

  • Independent hot water or on-board electric heating versions available
  • Triple safety patented design controls
  • Easy low cost maintenance – no ongoing maintenance contracts (unless requested)
  • Designed and manufactured in accordance to 2014/68/EU PED
  • Certified by relevant third party
  • Used materials certified in accordance to EN 10204 v3.1
  • All welding performed by coded welders to UNI EN ISO 15614-1:2008 and point 3.1.2 annex I directive 2014/68/EU PED and UNI EN 287-1:2012
  • Welded components are Hydrotested

Benefits:

  • Lower heavy ends / oil than direct heated vaporisers
  • Highly reliable components and low maintenance required
  • UK based technical support with expertise to carry out repairs & servicing
  • Commissioning, maintenance, and training services offered by Clesse UK
  • No liquid inside the vaporiser in the event of a system failure

  • Equipment is modular, each component can be replaced if necessary

Vaporiser Types

Feedout
In this setup, the vaporizer’s outlet is connected directly to the vapour space of the storage tank that provides the liquid LPG.

Feedback
In this setup, the vaporizer’s outlet is piped directly downstream to the distribution system.

Ecovap
LPG liquid is contained inside the coil, whilst hot water surrounds and is contained in the barrel.
• Ideal for Feedout operation

Vapeg
Water is contained inside the coil bundle, whilst LPG surrounds and is contained in the tube.
• Ideal for feedback operation.
• High efficiency compact design.
• Coils removable for inspection.

Electric
LPG is pre-heated by an intermediate fluid (water & glycol) which is heated by an EEX electric heating element with two thermostats, one for regulation of the temperature and the other for protection against overheating. It contains a water expansion vessel, with safety and control valves built–in. There is an EEX Low Level Water Switch to indicate the level of fluid in the system with an automatic air vent and a glycol pressure relief valve. The system is controlled via panel that operates from 2 pressure switches keeping a constant pressure in the vessels for use, and a second as a safety cut off, in the event that the pressure exceeds the design limit.

Independent Hot Water
LPG is pre-heated by an intermediate fluid (water & glycol) which is heated via a domestic or commercial boiler (situated in a separate boiler house). Heat control is not direct as the system uses a heat exchanger with a separate pump, operated from the control panel. It is also assembled with safety and control valves built in on the Liquid Gas inlet, operated by temperature and pressure from the water and glycol mix. Other valves on the heating side for safety are the automatic air vents and a glycol pressure relief, with temperature probes for visual indication. The system is controlled through a panel that operates the pressure switches. Pressure Switch 1 keeps a constant pressure in the vessels and Pressure Switch 2 acts as a safety cut off if the pressure exceeds limitations.
