Heat Recovery

HEATEX “AIR TO AIR” HEAT EXCHANGERS
“The Untapped Energy Source”

Heatex plate heat exchangers are recuperative cross-flow heat exchangers built from aluminium or stainless steel plates. Two neighbouring plates form a channel either for supply or exhaust air or gas. The supply air passes on one side of the plate and the exhaust air on the other side.

The heat is transferred through the plate from the warmer air stream to the colder air stream.

What Are Its Uses?

Energy recovered from any “Exhaust” air stream is returned to the process or building, thus reducing energy demand.

Applications include:

• Ventilation of;
  • Hotels
  • Clubs
  • Homes
  • Any high occupancy enclosed space eg… School Classrooms
  • Swimming Pools (to control condensation, odours & corrosion)
• Commercial Processes;
  • Clothes dryers,
  • Baking Ovens
  • Food Dryers
  • Kilns
  • Boiler flues

  • Any other industrial process up to 800oC

Heatex recovers Hot or Cold thermal energy, from any stale, foul, or polluted air.

Heatex can condense gasses or vapours from gas or air (ie… fumigation, or solvent gasses).

Heatex reduces the cost of “Catalytic Cleaning”, to meet industrial odour and pollution emission standards. (Enquire about our new “Low temperature” Catalytic Cleaning solution).

Indirect Evaporative cooling models (EVCO) cool air without refrigeration or increasing humidity & can improve the performance of air conditioning plants, by over 50%, even in climates with high humidity.

What Sizes are Available?

There is no size limit. From a small room to a high rise or major industrial application. Heatex have installed many, with “cores” over 60 metres wide.

How Efficient Are They?

Heatex produce standard models that can recover up to 98% of the energy from any air stream. up to 800°C.

Temperature Range

Two models available

1) up to 230°C

2) up to 800°C

Materials are Aluminium and all grades of Stainless Steel

How To Get An Appraisal For Your Application

Email or phone Avon Electric Ltd with the following information …

1. Describe your energy use process.
2. Hours of use. Payback depends on hours of use. Heat Exchangers may not be a viable investment, for example in a church hall, because of insufficient hours of use. However a hotel bar or industrial process dryer can achieve 100% payback in 6 to 36 months.
3. As much detail as possible about your process temperatures and exhaust air flow. For an accurate appraisal we need to know…. Air flow, (volume), temperatures and humidity for Exhaust and Supply air flows (we can arrange measurements if required).

We will provide a detailed computer generated data page on what the Heat Exchanger will do, in terms of kilowatts of energy recovered, and a budget quotation.
