Air-water heat exchangers

Energy recovery from hot airflows In the industry, heat is often generated as a by-product of the production process. With Läckeby air-water heat exchangers, you make this excess heat or warm process air pay for itself. Reusing heat is one of the most cost-effective and environmentally friendly investments. We offer robust and modular heat exchanger solutions with an excellent price/quality ratio. Our heat exchangers can be fully customized and integrated in your production process. Air/water heat exchanger The air/water heat exchanger from Läckeby was originally designed to protect the membranes used in water treatment plants and extend their life. The heat exchanger was designed to efficiently reduce the temperature of the air passing through the membranes. Over the years, the realization has grown that this unique product is also perfectly suited to recover heat from air flows coming from blowers. Moreover, it is also very suitable for heating ventilation air or low pressure water circuits. The compressed hot air circulates freely between a closed circuit consisting of a large number of copper tubes containing coolant. This allows a high content of heat to be recovered from the incoming hot air stream. Our air-water and sludge-water heat exchangers are ideally suited for preheating water circuits. This pre-heated water can be used internally. For example, water treatment in laundries or other industries where large amounts of hot water are required. Läckeby heat exchangers are very versatile, you can also use them as cost-saving applications for air conditioning or heating.

Septic Receiving unit

Processing septic material requires proper preparation of the material. It is important to remove fibers from the septage. Of course, fibers are unwanted in wastewater treatment plants and sludge processing plants. Lackeby Roto Sieve septic receiving units are suitable for separating fibers from septic material. Septage receiving units are very robust and user-friendly machines. Most importantly, the receiver is equiped with an internal feed. This way, the installation can easily handle high flow rates. When the sludge is delivered from tank trucks, high flow rates are reached in a short period of time. The Lackeby septic receiving unit with internal feed is perfect for this job. In addition, the machine is equipped with automatic flow control. Septic receiving units are not only suitable for the separation of septage, but can also be used for screening by-pass or overflow water. The installations are very reliable, have a long life span and low energy consumption. The advantages of a septic recieving unit - fast emptying of a tank trucks (15 min) - very high degree of separation - automatic flow control - life span of more than 20 years - maintenance-friendly - low energy consumption - No odor thanks to the sophisticated design - low spraying water consumption - Quick and easy inspection

Optimisation of pre-treatment at WWTP

The Gramat WWTP in France has significantly improved its pre-treatment process by installing a Lackeby Roto-Sieve® drum screen. The installation, with a capacity of 9,500 IE, processes an average of 60 m³ of influent per hour.

Energy from effluent

Effluent from wastewater treatment plants often still contains valuable heat. This heat can be recovered using heat exchangers.
