Refra manufactures pump stations for waterloop systems with the cooling capacity from 30 kw to 250 kW. These systems produce distributed cooling at different temperatures with a single condensing water loop. Together with Refra pump stations, the system creates a fully integrated refrigeration technology that eliminates the need for complex refrigeration systems and greatly simplifies installation work. Built on a super slim assembled galvanized steel frame with powder coating. Standard selection includes single or dual pump with inverter, glycol tank with filling pump, shut-off valves, control board with controller and necessary control sensors as well as a three-way valve, manometers and a coarse cleaning filter. Extra features, such as emergency heat exchanger with full controls or bubble filter separator can be combined. An additional heat recovery pump can also be added to extract maximum efficiency from the system.

Many imagine that stairsteps are made of solid wooden board. The stairsteps must be made of laminated dried wood with moisture content 8-10 %, lamellae width 5-8 cm. They would not curl, and would not crack, when stuck in this way. When making a stairstep, one should combine the colour of lamellae, especially of ash wood as it is not uniform, it is mottled – one end brown, while another one is bright. Surface coating of stairsteps can vary – from stain, oil, to oil stain. Usually, finishing colour is combined with the floor colour or interior elements, e.g., door. These solutions are very individual. We make only stairsteps too, i.e., it is not necessary to order the whole staircase. We can install stairsteps, according to your request, or sell without installation works. They are also available in our online shop. What is more, if standard stairsteps do not fit, we make stairsteps of your dimensions. Stairsteps are made within 2-3 weeks. Stairsteps are installed within 2-3 days.
