FLIPPER

Modular, compact liquid chillers / heat pumps

The FLIPPER series consists of high-efficiency, water-cooled chillers and heat pumps featuring a compact, modular design. The footprint of the unit casing fits within the dimensions of a standard Euro pallet (1200 × 800 mm), simplifying transportation, installation and servicing. The units are intended exclusively for indoor installation.

The units use scroll compressors controlled by frequency inverters, enabling precise capacity regulation. Plate heat exchangers ensure efficient heat transfer while reducing the required refrigerant charge. FLIPPER DUO units feature two refrigerant circuits connected to a common hydronic circuit via a dual plate heat exchanger (SWEP True Dual).

Two high-efficiency pumps controlled by variable frequency drives enable flow rate regulation on the primary evaporator and condenser sides. By connecting multiple units in parallel, a flexible heating and cooling system with a higher overall capacity can be configured.

Each unit is factory-tested in accordance with EN 14511 and supplied pre-charged with refrigerant and oil. Conformity assessment of the assembly is carried out in accordance with Directive 2014/68/EU on pressure equipment (PED).

*Number of compressors equals the number of independent refrigerant circuits

FLOW UNDER CONTROL

Factory-installed Grundfos MAGNA3 EC pumps provide benefits:

•  Stable evaporator flow under all operating conditions
•  Lower pumping energy consumption
•  Faster commissioning
•  Simplified installation

---

FLIPPER units can be connected in parallel, i.e. combined to create a flexible
system with a higher heating or cooling capacity. Such a configuration is
particularly suitable for retrofitting existing systems
(e.g. buildings with limited installation space).
