Buffer Tanks
Hydraulic separation for optimal heat pump efficiency. Our buffer tanks in SUS316L stainless steel protect your heat pump from short-cycling, reduce compressor starts and significantly extend system lifespan.
Product Advantages
Hydraulic separation for maximum efficiency and longevity of your heat pump system.
Hydraulic Separation
The buffer tank hydraulically decouples the heat generator and consumer circuits. The heat pump operates at optimal working points, avoids short-cycling and minimises compressor starts.
German Quality Design
Designed in Germany — minimalist and timeless. Harmonises with modern plant rooms and is produced in individual colours and cladding on request.
Triple-Strength Welds
Double-sided formed welding technology — three times stronger than industry standard. SUS316L material guarantees corrosion resistance and decades of trouble-free operation.
INCOLOY Immersion Heater
High-grade INCOLOY immersion heater for optimal heat transfer and long service life — resistant to scale deposits and corrosion even in hard water conditions.
Optimal Thermal Insulation
Polyurethane high-pressure foam insulation minimises heat loss in the buffer tank. Energy-efficient operation even during extended standstill — tested with infrared inspection.
Wide Size Range
From 40 to 500 litres for all system sizes — from single-family homes to multi-family buildings and small commercial premises. Available in SUS304, SUS316, A0444, SUS2205 and SUS2304.
