AIR/WATER COOLING – HEAT EXCHANGERS

Since the thermal load continues to increase, conventional cooling methods eventually reach their physical limits. It can happen that thermal load limits within a cabinet are such that some height units must go unused.

The solution: heat exchangers installed close to the heat source not only increase the cooling capacity but also improve the redundancy of the data center. With intelligent monitoring, air conditioners can quickly respond to the working load of the equipment, so enabling additional savings.

If air/water heat exchangers are fitted, a false floor is not strictly necessary; this makes for a further saving that contributes to the overall reduction of costs. Hot-swap fans and redundant power supply units give you security and ensure system availability.

In-row heat exchangers Varistar SHX30

Active heat exchanger for containment systems with a cooling capacity of up to 30 kW. This in-row heat exchanger is fitted into a row within the aisle containment. This enables optimal scalability with a view to planning for the cooling capacity and the redundancy of the system.

In this combination an active heat exchanger, integrated into an 800 mm wide cabinet, has the smallest space requirement on the market. The closed system reduces the noise level and controls itself by means of the thermal load. With a maximum capacity of 40 kW this heat exchanger is also suitable for high-performance computing (HPC).

Multiple cabinets can be arranged side by side to create a closed system. Thanks to the small space requirement, the reduced noise level and the ease of creating redundancy, this heat exchanger is particularly well suited for medium-sized data centers or for cooling hot spots.

The passive heat exchanger is situated in the rear door of the cabinet and cools the exhaust air before it returns to the room. Thanks to its high surface area this totally passive system can offer high cooling capacities of up to 30 kW. Heat exchangers in the rear door are suitable for high-performance computers with a relatively uniform server structure throughout the entire cabinet height.
