We are experts in designing for unique applications and the use of multiple ERD devices.  We compliment these systems with all types of cooling & heating solutions and airflow tempering technologies. We provide from the simple to the advanced unitary ACCU and heat pump systems.  Control of our unit can be through our cooperation with BAS technicians or a complete factory provided tested sequence. 

XeteX Exchangers

XeteX exchanger

Depending on your design conditions, space restraints, or ducting configuration, one of XeteX’s standard Heat-X-Changer® designs may already be well suited for your application. If, however, you have specific needs that require a more specialized system, a fully-customized unit can be built.

  • Rotary
    The rotor is assembled from alternate layers of flat and corrugated thin sheet aluminum.  The smooth channels result in a very low pressure drop and minimize the risk of fouling by dirt or dust—dry particles up to 900 microns wide can pass freely through the rotor without clogging.

The rotor is also self-cleaning; debris caught on the wheel surface will be blown off when the wheel rotates to the other side of the exchanger and encounters the airstream blowing in the opposite direction.  If additional cleaning is necessary, the rotor face can be cleaned with compressed air, a vacuum cleaner, water, low pressure steam, or a mild detergent.

  • Flat Plate Crossflow
    In flat-plate heat exchangers, two airstreams cross by each other. In typical HVAC applications:

    • One of these airstreams consists of air being removed from the ventilated space. The part of this airstream upstream of the exchanger is commonly called “return air.” When it emerges from the opposite end of the exchanger, is called “exhaust air” and is typically discharged outdoors.
    • The other airstream is the fresh outdoor air being supplied to the ventilated space. The air in this airstream upstream of the exchanger is called “outdoor air.” On the opposite end of the exchanger, the fresh air flowing out is called “supply air” because it is supplied to the ventilated space.
    Flat Plate

    The flat plates can be made of various materials (e.g. aluminum, plastic, resin coated paper, etc.). In the exchanger, they form a stack, aligned parallel to each other and separated by a certain spacing. The two airstreams flow through the channels formed between the flat plates. Each airstream flows into alternating channels—i.e., supply air in one channel, return air in the next, supply in the one after that, etc.—so while they pass near each other, they never mix. Sensible energy from the warm air flowing through one side of the exchanger is transferred to the cold air flowing through the other. Some flat plate exchangers also transfer latent (moisture) energy from the high-vapour-pressure side to the low-pressure side of the plates.

    In applications such as process cooling, the return air is used to pre-cool incoming fresh air. In non-HVAC applications such as equipment cooling, one air flow can operate in a closed-loop providing contaminate-free cooling, while the other airflow is simply scavenger air—outdoor air brought through the exchanger to cool the closed-loop air, then discarded outdoors.
