Energy savings contribute to reduced CO2 emissions, meeting modern environmental standards. RS models L160-L250 – it is the optimal choice for companies that seek energy efficiency, flexibility and reliability in operation.

Heat recovery in CompAir L-Series compressors

Heat recovery in CompAir L-Series compressors is an advanced technology that allows you to convert waste energy into a valuable resource, significantly reducing operating costs and increasing energy efficiency. During the air compression process in rotary screw compressors, up to 70% of the energy consumed is converted into heat, which is usually lost through cooling systems such as fans or water circuits. These systems not only waste additional energy to remove heat, but also lose a potentially useful resource. The CompAir heat recovery system captures this heat (temperature 70-90°C) and directs it to useful purposes, such as water heating, space heating, steam generation or material drying, which reduces the need for additional energy resources.

The recovery system can be installed at the factory or added to existing compressors as a retrofit. It includes all the necessary components - piping, fittings and controls - to use the heat efficiently. For example, a 160 kW compressor can recover up to 112 kW of thermal energy, which can cover a significant part of the company's hot water or heating needs. In industrial processes, such as cleaning, washing or material processing, hot water is indispensable, and in the cold season the recovered heat is effectively used to heat workshops or warehouses. In the woodworking, textile or food industries, heat is used to dry products, which reduces the cost of specialized equipment.

The economic benefits of heat recovery are impressive. For example, Just Trays achieved annual savings of £23,000 after implementing the system, and otherwise reducing natural gas consumption by 15% brought €8,000 savings every year. The payback period of the system is usually 1-3 years, depending on operating conditions and energy costs. After this period, the savings become a net profit. Environmental benefits include a significant reduction in CO2 emissions, as recovery replaces traditional heating methods such as gas combustion or electrical heating, contributing to sustainability and compliance with environmental standards.

The recovery system integrates with the Delcos XL controller, which provides real-time monitoring and optimization of heat use. The combination with building management systems (BMS) allows automatic coordination of the heat recovery operation with other heating or ventilation systems. The combination with the RS model is particularly effective.we are variable speed, where a stable temperature increases the recovery performance. IoT technologies open up prospects for intelligent control, allowing you to predict heat demand and optimize system operation. CompAir L-Series heat recovery – is not only a technological solution, but also a strategic investment in energy-efficient, cost-effective and environmentally responsible production.
