HOLTOP fresh air handing unit recuperator plate heat exchanger price

High efficiency cross flow air to air sensible heat exchanger

Sensible heat recovery air to air heat exchanger is used in comfortable air conditioning ventilation system and technical air conditioning ventilation system. Supply air and exhaust air totally separated, heat recovery in winter and cold recovery in Summer. Two neighbor aluminum foils form a channel for fresh or exhaust air stream. Heat is transferred when the air streams flow crossly through the channels, and fresh air and exhaust air is totally separated.

Features of cross flow air to air plate heat exchanger

1. Aluminum foils cross flow sensible heat exchanger

2. Heat recovery efficiency up to 75%

3. 2-side press shaping, double folded edge.

4. Resistance of pressure difference up to 2500Pa

5. Under pressure of 700Pa, air leakage less than 0.6%

Material type of cross flow air to air heat exchange core

B series (standard type)

Heat exchanger is made of pure aluminum foils, with galvanized end cover and aluminium alloy wrap angle. Max. air temperature 100°C, it is suitable for most of the occasion. 

F series ( Anti-corrosion type)

Heat exchanger is made of pure aluminum foils cover by special anti-corrosion material, with galvanized end cover and aluminium alloy wrap angle. it is suitable for the corrosive gas occasion.

G series (high temperature type)

Heat exchanger is made of pure aluminum foils, with galvanized end cover and aluminium alloy wrap angle. Sealing material is special and allow the Max. air temperature to be 200°C, it is suitable for special high temperature occasion.

INSTALLATION NOTES

Condensing water pan

When designing heat recovery functional section in air handling unit, under the heat exchanger should add the condensing water pan, in case of disorderly flow of condensing water

Heat exchanger vertical installation

When outdoor temperature is lower than indoor temperature, during heat exchanging if RA temperature is low enough (relative humidity 100%) then condensing water will come into

being, once there is condensing water, heat exchange area inside heat exchanger is decreased, efficiency become lower and pressure drop increased, in order to eliminate the condensing

water in time, heat exchanger vertical installation like the picture below is the best choice.

Aluminum sensible heat recovery heat exchange core specification

Installation

Pattern 1 and 2, to increase the heat exchange area, suitable for occasions requiring higher heat recovery efficiency,
however, air resistance will increase accordingly.

Pattern 3 and 4, to increase the front face area, suitable for occasions requiring large airflow, both air resistance and

heat recovery efficiency remain stable.

Pattern 5, to increase both front face area and heat exchange area, suitable occasions requiring higher heat recovery
efficiency and large airflow.

Applications

Installed in air handling unit

Holtop plate heat exchanger can be used in the air handling unit (AHU) as a main part of the heat recovery section, and the bypass can be built in when required.

Installed in ducts

It can also be installed in the ducts of ventilation system as a main part of the heat recovery section. The installation is very flexible.
