2 eat exchangers One concept, two systems with very different operating methods Air/water heat exchangers cool the enclosure internal air via integration into an existing cooling water circuit or connection to a recooling system In this way, extremely high heat loads may be dissipated Air/air heat exchangers utilise the cooler ambient air to cool the air in the enclosure interior Based on the counterflow principle, the completely separate airflows are routed through the heat exchanger module via high-performance fans This prevents the ingress of dust from the environment into the enclosure interior eat exchangers Air/water heat exchangers Benefits, technical details 06 Wall mounting, useful cooling output 600/000 W 08 Wall mounting, useful cooling output 50/540 W 0 Wall mounting, useful cooling output 50/3000/0 W Roof mounting, useful cooling output 900//0 W 4 As a side panel for 600 mm deep TS 8 enclosures, useful cooling output 700 W 6 Air/air heat exchangers Benefits, technical details 8 Wall mounting, specific thermal output W/K 0 Wall mounting, specific thermal output 90 W/K Wall mounting, specific thermal output W/K 4 Wall mounting, specific thermal output 4 69 W/K 6 Roof mounting, specific thermal output 66 W/K 8 Practical example of an air/water heat exchanger In all areas with extreme ambient conditions, enclosure and climate control components are subject to special requirements This applies, for example, to metal foundries, engine factories and the chemicals and metal-working industries In such situations, low-maintenance air/ water heat exchangers are used as efficient all-rounders Either fed from existing cooling water networks or from separate recooling systems, these products contribute to an ideal climate inside the enclosure The cooling water absorbs the heat inside the heat exchanger and conveys it to the corresponding cooling system In this way, even small rooms are not subject to additional waste heat from the enclosure, and the electronics inside the enclosure are effectively protected Wood-processing industry Air/air heat exchanger (wall-mounted) Practical example of an air/air heat exchanger In the paper and wood-processing industries, for example, particular requirements are placed on climate control components They ensure good ventilation inside the enclosure, and heat dissipation out of the enclosure At the same time, they also prevent the ingress of super-fine dusts Air/air heat exchangers are ideal for this purpose, since they effectively dissipate the heat from the enclosure with their two hermetically separate air circuits based on the reverse current or counter-current principle, and prevent the ingress of ambient air into the enclosure The requirement for the use of air/air heat exchangers is that the ambient temperature must be below the enclosure internal temperature Standard control units such as thermostat, hygrostat and speed control for noise minimisation, as well as special C variants, extend the range of applications, eg to the railway sector 05

3 Air/water heat exchanger Benefits, technical details The air of the enclosure interior may also be cooled to below the level of the external temperature, if required, by using cooling water from a central recooling system The ingress of dust from outside into the cooled enclosure is prevented The waste heat from the enclosure does not raise the temperature of the ambient air, provided the heat exchanger and cold water supply system are spatially separated from one another Performance benefits of air/water heat exchangers Useful cooling output from 600 to 0 watts in three mounting variants: Wall mounting Roof mounting Integrated in the TS 8 side panel This installation form uses the space behind the side panel of the TS 8 Central cooling as cold water supplier By integrating the air/water heat exchangers into an existing cooling water circuit or connecting to a central recooling system, the necessary heat loss can be dissipated with exceptionally low energy costs Also suitable for use in extreme conditions Ideal at any installation site If direct dissipation of heat loss to the ambient air is not desired or ineffective due to the confined space, the air/water heat exchanger may offer an ideal solution Particularly by separating the exchanger from the recooling system, highly individual and effective cooling solutions for individual enclosures or bayed enclosure suites may be achieved Example: Parallel connection of air/water heat exchangers with cold water supply via a recooling system Overflow valves and bypass control should be integrated into the recooling system and the customer s own pipeline system respectively 3 Recooling system Air/water heat exchanger, roof-mounted Air/water heat exchanger, wall-mounted Additional cooling water circuit for machine cooling Effective in extreme conditions Air/water heat exchangers may even be used in particularly extreme ambient temperatures from + to +70 C Even extreme levels of contamination in the ambient air, eg with dust and oil, do not affect functioning igh heat losses are dissipated in the most confined spaces, without emitting them directly to the ambient air A high operating ratio is achieved, thanks to the large surface area of the heat exchanger unit Also available in stainless steel Roof-mounted and wallmounted air/water heat exchangers are available with all water-carrying parts made from stainless steel 457 (V4A) for use in extreme conditions 06

4 Installation and service benefits Compact and lightweight Air/water heat exchangers have a low weight and a comparatively low volume in relation to the heat loss to be dissipated As a result, they are easily mounted on vertical enclosure surfaces or on the roof Air/water heat exchanger integrated into the side panel This side panel combines effective heat dissipation with minimum space requirements It may be used in all 600 mm deep, 800 mm/0 mm high TS 8 enclosures Virtually maintenance-free Because the ingress of ambient air into the heat exchanger is prevented, dirt is unable to penetrate Control of the air and water circuit is electronically monitored Air/water heat exchanger Control and safety included Roof-mounted heat exchanger control/monitoring The enclosure internal temperature is monitored by means of a thermostatically or electronically controlled magnetic valve It regulates the throughput of cooling water If the enclosure interior temperature rises above the set level, the floating change-over contact raises the alarm Leak monitoring of roof-mounted units In order to ensure that the enclosure interior is not at risk from cooling water, the sensor reports a leak in the event of water in the corrosion-resistant base tray igh protection category Thanks to the sealed design, a protection category of IP 55 to EN 60 59/09 is achieved Condensate management Any condensate arising is discharged via the / tube connector and a discharge hose, which should be laid with a gradient ensuring that there are no kinks In order to avoid increased condensation, the cooling water temperature should be adapted to match the required cooling output Any condensate occurring may be disposed of using an external electronic condensate evaporator Safety instructions When installing the device, the condensate discharge must be routed out of the enclosure! In order to avoid frost damage, the minimum permissible water temperature of + C must not be undercut at any point in the water cycle! It is vital that the manufacturers consent is obtained before adding anti-freeze! uring storage and transportation below freezing point, the water cycle should be drained completely using compressed air! Only set the thermostat as low as is strictly necessary, since undercutting the dew point with a falling water inlet temperature will result in condensation! It is very important that the enclosure is sealed on all sides (IP 54), particularly the cable entry (condensation)! Benefits: Useful cooling output from 600 to 0 watts Suitable for use even under extreme conditions and ambient temperatures of up to +70 C Also available with all water-carrying parts made from V4A System for TS 8 integrated into the side panel Important Air/water heat exchangers should always be used in conjunction with recooling systems or a cooling water cirucuit For calculation formulae and water quality requirements, please see page 88 or refer to the Internet at wwwrittalde 07

15 Air/air heat exchangers Benefits, technical details The requirement for use of air/air heat exchangers is that the ambient temperature must be below the enclosure internal temperature ust and any aggressive ambient air is unable to enter the enclosure interior, thanks to the two separate air circuits Outstanding performance and design In all situations where the ambient air is sufficient for cooling, air/air heat exchangers offer effective, energy-saving solutions The high specific thermal output is attributable to the special construction and functional design of the heat exchangers: A large heat exchanger area with compact dimensions Exceptionally conductive materials and connections Fans that may be controlled separately Optimum flow conditions Variable output from 75 to 90 W/K Identical mounting cutouts for various specific thermal outputs facilitate easy adaptation of the output to various requirements Wall-mounted cooling units are likewise compatible with this interface This means that the same interface on the enclosure may be used for heat exchangers and cooling units of different output categories Flow and siting conditions Internal/external mounting Air/air heat exchangers may optionally be mounted on the outside of the enclosure or inside the enclosure The slimline design facilitates external mounting on the door, rear panel and side panels The range also includes a special heat exchanger for roof-mounting By diverting the waste air upwards, this prevents the creation of disruptive airflows in front of the enclosures The fans in the internal and external circuit may be activated separately and thus adapted ideally to the ambient conditions External mounting Internal mounting 8
