THERMO-SIPHON Heat Exchanger

Designed using the natural thermo-siphon on the domestic hot water side, our THERMO-SIPHON Heat Exchanger not only provide faster heating at a greater capacity than traditional sidearms, they prevent cross contamination in potable water application.

While the capacity of traditional sidearm heat exchanger is determined by the length of sidearm tubes and their heat transfer efficiency is comparitively very low.Instead of using two bare copper tubes,our fin-enhanced heat exchangers made of stainless steel and will have high heat transfer efficiency resulting from the utilization of an internal finned tube.This fin-enhanced design has a surface are five to eight times bigger than the bare tube design and produces significant turbulence on the system side.Our fin-enhanced sidearms provide a larger capacity and faster hearing using a shorter unit.Fin-enhanced sidearms are available upon request.

Concerns about cross contamination of potable water has forced several countries to enact several
regulations designed to prevent this from happening.Double wall sidearm heat exchangers present
the most effective means of protection from cross contamination.Our vented double walled sidearm
meets all the criteria of these regulation.

Advantages:

• Extremely Efficient

• Compact Size and Easy Install

• Easy Cleaning Mechanically

• No Complain for Hot Water

APPLICATIONS

Outdoor wood boilers

Solar hot water heating

Domestic hot water heating

Floor heating

Typically the domestic water is circulated by means of the thermosiphon principle which saves on the cost of a pump and the associated electrical costs,In cases where faster heat recovery is required the domestic hot water should be circulated by means of a pump.Pump circulation will typically provide a heat recovery 3 to 4 times greater than thermosiphoning.We offer the following three models:

Model	Nominal Capacity		System Water				DHW Water				DHW Side	System side
