80+ heat exchanger models for gas/wood/pellet fired, indoor/outdoor boilers, furnaces, stoves and heaters.

Types

Copper Brazed Plate Heat Exchangers
The BPHE type is one of the most popular and common type of heat exchangers on the market today. With pressure rating as high as 435 psi and operating temperature range of -256°F to 437°F, it's uses and applications are mostly limited only by compatibility of liquids with it's materials (copper and steel).
Among the top advantages of the BPHE over other heat exchanger types are its compact size, lower cost and superb efficiency.
 

Aluminum Finned Copper Coil Heat Exchangers
Also known as "water to air" or "air to water" heat exchangers, these units are applicable to a wide range of projects, from residential air and water heating, to commercial heat recovery, oil cooling and many others.
Brazetek design ensures durability (18-gauge casing vs. competition's 20-gauge) and efficiency (high purity aluminum fins permanently bonded to the copper tube surface) of all models for years or reliable, trouble-free operation.
 

Stainless Steel and Titanium Shell & Tube Heat Exchangers
When liquid viscosity, superb corrosion resistance or high flow rates are important factors, Brazetek Shell and Tube heat exchangers offer the solution. Two series available from Brazetek include the ST series (316L Surgical Grade Stainless Steel) and STX (Titanium).
All units are seam-welded and are compatible with an extremely wide range of liquids, including salt water (STX only).
Popular residential uses of shell & tube units include heating of pools and spas as well as solar heating.

Applications

Indoor & Outdoor Wood or Pellet Boilers and Stoves

Among the most common heat exchangers used in combination with boilers are brazed plate type and shell and tube type. Most typical uses include transferring heat from hot water produced by a boiler or stove to an indoor heating system, hot water storage system or a snow melting system.
Brazed plate heat exchangers (BPHE) are the popular choice for any of the above since they offer highest efficiency with minimal footprint and lowest overall cost.
Residential heating systems - whether radiant or hydronic, generally require a 4"x12" or 5"x12" models with plate size corresponding to the output of the boiler.
Domestic hot water - heat exchanger sizes such as 3"x8" and 4"x12" may be used for hot water recirculation and heating purposes in most residential applications (up to 80 gallon storage tanks). For larger applications, see Quick Sizing Guide (pdf).
Snow melting - heat produced by the boiler can be used for an outdoor snow melting or roof de-icing system. Since such systems generally contain 50% glycol for freeze prevention purposes, a BPHE effectively separates this solution from the hot water produced by the boiler.

Indoor & Outdoor Wood or Pellet Furnaces

Brazetek aluminum finned coil air to water heat exchangers can effectively absorb the heat produced by the furnace and transfer it to water, which can consequentially be used for baseboard, radiant floor heating or similar application.
A large selection of models with sizes ranging from 12"x12" to 24"x24" ensures compatibility with nearly every residential furnace type or plenum size available.

Heating of Domestic Hot Water

A properly sized indoor or outdoor boiler can be used to heat the domestic water without the need for an external (stand-alone) gas or electric water heater. Installing a brazed plate heat exchanger allows to separate the non-potable (boiler) water from domestic water and store the later for future use.
The heat exchanger is normally sized based on the storage tank size, with 3"x8" (larger models) and 4"x12" units being most common for 40, 60 and 80-gallon storage tanks.

Spa & Swimming Pool Heating

Large volume of water (which is often chlorinated) typical for swimming pools requires a heat exchanger which can handle the high flows required to maintain the pool water temperature. Brazetek shell and tube heat exchangers are the perfect solution. Use ST (316L St. Steel) for plain and chlorinated water pools and STX series (Titanium) for salt water.

Hydronic and Radiant Floor Heating

Since most wood and pellet boilers on the market are non-pressurized type, the hot water they produce is highly oxygenated. Such water cannot be used for traditional home heating applications, as it will corrode the cast iron components such as piping, circulator pumps, air scoops, etc.
To separate these two mediums, a brazed plate heat exchanger is used.

Forced Air Heating

Brazetek HTL series water to air heat exchangers can be coupled with a fan or a blower to create a forced air heating unit. This option is well suited for heating garages and workshops and can be done at a fraction of the price of the pre-manufactured unit heater.
