Heat Pipe Heat Exchanger
The operation of a heat pipe is easily understood by using cylindrical geometry, as shown “below/next to…”. The length of heat pipe is divided into three parts: the evaporator section, adiabatic sections (transport) and condenser section. A heat pipe may have multiple heat sources or sinks with or without adiabatic sections depending on specific applications and design.
Heat applied externally to the evaporator section is conducted through the pipe wall, where it vaporizes the working fluid. The resulting vapor pressure drives the vapor through the adiabatic section to the condenser, where the vapor condenses, releasing its latent heat of vaporization to the provided heat sink.
Different types of working fluids such as water, acetone, ammonia and oils can be used in heat pipes based on required operating temperature.

FACTS & BENEFITS
HIGHLY SCALABLE, CUSTOMISABLE & CONFIGURABLE
Modular design allows on-site assembly. Can be designed for future expansion, to meet specific application or operational needs.
EASE OF CLEANING & MAINTENANCE
Can be maintained on-site (no uninstall). Manual/automated cleaning systems.
Fast reaction time, offers different control options and suitable for sensitive apparatus: does not require preheating.
Comparing to traditional waste heat recovery boilers, the heat pipe technology reduces installation volume and reduces installation costs.
LOW PRESSURE DROP
Low parasitic load means less capital and running cost on fans and greater energy recovery possibilities.
ISOTHERMAL OPERATION – NO HOT OR COLD SPOTS
Eliminates cold corners and condensation. Allows greater energy recovery. Better Longevity for thermal oil.
ROBUST MATERIALS AND LONG LIFE
Design allows pipes to freely expand and contract, thus no thermal stress on structure. Thick pipe walls resist erosion/corrosion.
Use of smooth pipes allows exchangers to be used in high particulate or oily applications.

OUR SERVICE IS PROVIDED AS AN AUTHORIZED TECHNOLOGY PARTNERSHIP WITH ECONOTHERM UK LTD.
The company was formed in 2007 in order to develop, design, manufacture and deliver heat pipe waste heat recovery units for industrial applications.
The company acquired the intellectual properties of a company called Transterm, which included and culminated into 25 years of extensive research and development in the field of heat pipe technology. Econotherm has since patented number of heat pipe technologies for onshore as well as for offshore applications.
With now over 300 successful implementations, Econotherm has built up an remarkable list of blue-chip references. Econotherm equipment are currently operating in 12 countries and 8 industrial sectors with a range of power from 10 kW to 15 MW. Our onshore customers claim that in their projects the payback time has been less than two years.
