Rotary heat exchanger

GreenMaster-@ uses a rotary heat exchanger, which provides very high efficiency and has the advantage of smaller dimensions and lower cost compared to GreenMaster-XXL.

However, there is an important factor to consider when using GreenMaster-@. Since the rotor can transfer odors through its brush seal, it's essential that the premises to be ventilated through the same unit have relatively similar activities. If there is a significant difference in odors or pollutants between the premises, they can be transferred through the rotor.

GreenMaster-@ comes in 13 standard sizes and can be customized to customer-specific requirements for larger sizes and configurations. The unit can be used both indoors and outdoors and can be supplied with or without control equipment.

A dry efficiency of up to 86% according to the standard SS-EN308:1997 is possible for this product. This means that a high proportion of the energy supplied to the fan is converted into airflow without adding moisture to the air.

High-performance fans with EC/PM (Permanent Magnet) motors are a crucial part of the GreenMaster system. EC motors are known for their high efficiency and energy savings. EC/PM motors are even more efficient but can be more expensive. The choice of motor depends on the customer's needs and budget.

There is also the possibility to choose different corrugation heights in the rotary heat exchanger to optimize SFP (Specific Fan Power) against efficiency. SFP is a measure of the fan's efficiency and is defined as the total energy consumption to move air through a unit of airflow. A lower SFP indicates higher efficiency and lower energy costs. By selecting the right corrugation height, you can optimize SFP and efficiency to achieve the best results for a specific application.

GreenMaster units are generally delivered in sections and are divided into blocks for easier transport. This makes installation easier and faster, especially in tight spaces where it can be challenging to maneuver with large units.
