High heat output from Starfin heat-pipes
Starfin heat-pipes heat quick and have about 80% less water volume than traditional welded steel pipe systems. Because there are less pipes, you have less shadowing and weight to support. Also, you never have to paint Starfin because it won't rust. Special fittings make installation a breeze!

Heat Exchanger

Systems

Occasionally, one water supply needs to be separated from another, but heat needs to be transferred between the two. Also, if a steam system is present and desired as the heat source for a hot water heat delivery system, then in these situations, TrueLeaf’s engineers will provide a heat exchanger.

We provide heat exchangers in four styles:

Brazed Plate Heat Exchangers:
These are very compact and cost effective units that can provide an amazing amount of energy transfer in a very small package. Imagine a few hundred thousand BTU’s coming from a unit the size of a cigar box! Embossed plates of stainless steel are attached together forming counter-flowing water passages, supply and return connections are provided for each "side".

Plate and Frame Heat Exchangers:
Similar in concept and design, these heat exchangers are "rack" style units that can be custom-assembled to match specific project needs. Individual embossed "plates" are bolted together on a "frame" to provide an optimized heat transfer solution that is also expandable as needs change.

Shell and Tube Heat Exchangers:
These are the most "conventional" greenhouse heat exchangers we offer. Typically, we’ll use these in steam to water applications. The steam is dispersed into the "shell", which is a cast iron, bullet-shaped vessel. Bolted into the end are the "tubes", which are typically copper. These tubes are where your heating system water circulates to pick up the heat being extracted from the steam.

The "Eliminator" (Coil-in-Tank Heat Exchangers):
We provide these a lot for irrigation preheating loads. A tank is providedwhich has an integral "coil" that is typically used for circulating water from your greenhouse central heating system. The heat from this coil is imparted into the tank and then stored. Heated water is then delivered directly to your plants in the form of warm irrigation. Sometimes we’ll store very warm water in the tank (160° or more) and, using an automatic tempering valve, we’ll "mix" it with cold fresh water to deliver the optimum desired temperature to your plants. This way, we can store a tremendous amount of energy in a smaller tank.
