Pool air dehumidifiers MSTR / MSPR series

High-efficiency air dehumidifiers MSTR / MSPR are designed for comprehensive control of temperature, humidity, heat recovery and ambient air conditioning in roofed swimming pools and corrosive environments.

Principle scheme

1. The mixed-flow plate heat recuperator allows recovering heat from the exhaust air, which is used to heat up the supply air. Pool version (standard): aluminium fins with protective coating.

2. Remote air condenser (for MSTR models, max. distance 30 m). The condenser dissipates the heat produced during dehumidification into the outdoor environment to prevent the ambient from overheating. The unit is used as an air conditioner.
3. The desuperheater connected in series to the compressor allows reducing the air temperature at the discharge into the pool, while recovering the refrigerant superheating energy by heating the water. It is available in versions designed either for process or chlorinated water (stainless steel AISI 316L).

The MSPR / MSTR units are ideal for swimming pools that not only require dehumidification but must also renew the indoor air without dispersing heat outdoors. The units of the MSPR / MSTR series are designed for use in small, medium and large swimming pools, where regulation of the humidity level and/or prevention of condensation phenomena is required, where a constant air exchange is necessary, even with 24-hour operation. The high efficiency recuperator guarantees efficiencies of up to 80% and the structure is particularly suitable for environments where there is the presence of corrosive substances such as chlorine.

The MSPR/MSTR range uses only EC radial fans with built-in inverters with high energy efficiency. Mycond has developed sophisticated adjustment software to set, measure and control the air flow rate of the MSPR/MSTR dehumidifiers, eliminating any problems arising from incorrect calculation of the pressure drop in the ducting, thus making the installation of the dehumidifier and the commissioning of the system extremely simple and fast, reducing installation time and costs. These units are designed to be connected to rigid ducting. The series consists of 20 models, ranging from 100 L/day and 900^m3/h to 4.600 L/day and 35.000^m3/h.
