COOLflow 4E PRODUCT RANGE FREE AIR COOLING FROM THE FREE AIR SPECIALISTS GUARANTEED TO SIGNIFICANTLY REDUCE CARBON EMISSIONS & DELIVER ENERGY SPEND SAVINGS OF UP TO 95% The COOLflow 4E range has been developed over a decade to offer market leading free air cooling solutions. Versitile options means there is a product to suit almost any application, in terms of cooling capacity, power supply, and filtration, as well as internally or externally installation and mechanical cooling add on modules.
& PLUS PRINCIPLES OF OPERATION External fresh air is drawn in via COOLflow 4E generating a positive pressure within the space, thereby eliminating the potential for outside contaminants to be drawn in without being filtered. The temperature inside the cabin is generally 5-10 C higher than ambient due to the heat generating equipment inside, and this warmer air is exhausted through a passive gravity louvre positioned at the opposite side of the equipment space. As the air passes through COOLflow 4E it is filtered by the COOLfilter 4E patented filter system, ensuring a clean and safe cabin environment. COOLfilter 4E 2.0 F7 MAINTENANCE FREE FILTRATION The next generation of COOLfilter 4E has been fully optimised to provide the ultimate in maintenance free filtration. Third party tested to BS EN 779:2012, this latest offering from 4energy builds upon a decade of filtration experience to offer the industries only F7 maintenance free filter. COOLING DONE QUIETLY Designed to be environmentally friendly, PLUS and Force remain quiet even under the most difficult of cooling requirements.

Through increasing the range of operating conditions, technical rooms and estates can be maintained at optimum operating conditions all year round. TEMPERATURE SETPOINT External Temperature Internal Temperature (COOLflow Full system) TIME Internal Temperature (Free air only) PRINCIPLES OF OPERATION During normal free air operation, external fresh air is drawn in through the COOLflow Force PLUS via weather louvres on the front of the Full System module. In recirculation mode, the actuated damper plate is rotated through 90 to allow air to be drawn into the COOLflow from the equipment room and through the evaporator coil. As no positive pressure is created in the space the gravity louvre exhausts remain closed stopping any contaminants from being drawn in.
