3 Modularity = More units in one system

4 Basic dimensions: Length 2400 mm (3 racks 80cm, or 4 racks 60cm) Height 600 mm Depth 400 mm on racks 3 2

5 Steel / Aluminum lightweight construction Horizontal heat exchanger water cooler 2 or 3 energy saving axial fans with EC motors 2-way or 3-way valve for precise waterflow control Temperature sensors Multiple security Advanced control Easy communication

6 Parameter unit 2 3 Dimensions (L x D x H) mm 2400 x 400 x 600 Number of EC axial fans Maximum airflow m 3 /h Power consumption W Current A 3,12 4,86 Total cooling capacity under nominal conditions (air 35 C, 25 % rh; water 10/15 C; above dew point) Net cooling capacity under nominal conditions (air 35 C, 25 % rh; water10/15 C; above dew point) kw 38,5 48,0 kw 37,8 46,9 Outlet air temperature under nominal conditions C 19,5 21,2 Water flow unit under nominal conditions ltr/h Water pressure drop under nominal conditions kpa 31 42

7 3 Cooling capacity 47 kw (air 35 C; water 10/15 C) Power consumption only 1100 W for 3 x 80cm rack 5-16 kw/rack for 4 x 60cm rack 4-12 kw/rack Air flow m 3 /h 2 Cooling capacity 38 kw (air 35 C; water 10/15 C) Power consumption only 710 W for 3 x 80cm rack 4-13 kw/rack for 4 x 60cm rack 3 9,5 kw/rack Air flow m 3 /h

8 Security points Stainless steel condensate pan under heat exchanger Steel security sump tank integrated in the casing Tube-in-tube safety drainage Droplet eliminator after cooler Security metal filter front of cooler Water level sensor Water leakage sensor (rope water sensor) Signal for solenoid valves (option)

9 Accessories Condensation predicting sensor Air humidity sensor Condensate pump ModBus RTU communication card SNMP or BacNet communication card Transport lugs (eyebolts) Transport handles

10 Financial effect: 1. Floor area saving 2. Energy saving Example: - 16 racks 600mm, depth 1000mm, height 42U - contained cold aisle - 35 C in hot zone, 25 C in cold zone - Chilled water system (10/15 C) - heat load 6kW/rack (total demanded cooling capacity 96 kw) - requested redundancy n+1

12 CRAC (CW) CoolTeg Plus (CW30) CW 3 units (Stulz ASD 420CW) cooling capacity 53 kw air flow m 3 /h dimensions 950 x 900 mm consumption 1,8 kw Occupied floor area = 2,6 m 2 Total consumption 3,6 kw (2 running units) 6 units CoolTeg Plus CW30 cooling capacity 21 kw air flow 3800 m 3 /h dimensions 300 x 100 mm consumption 0,77 kw max (0,3 kw at capacity 96/6=16 kw per unit) Occupied floor area = 1,8 m 2 Total consumption 1,8 kw (6 low-speed running units) 4 units 2 cooling capacity 38 kw air flow m 3 /h) dimensions 2400 x 600 mm consumption 0,7 kw max (0,2 kw at capacity96/4=24 kw per unit) Occupied floor area = 0 m 2 Total consumption 0,8 kw (4 running s)

13 Financial effects: 1. Floor area saving Floor area per unit Number of units Occupied floor area Floor area price Financial lost (m 2 ) (pcs) (m 2 ) ( /m 2 /year) ( /year) CW CoolTeg Plus 0,3 6 1, CRAC CW 0,9 3 2, Expected price of one footprint (0,6m 2 ) is 500 per month.

14 Financial effects : 1. Energy saving Indoor units consumption Number of units Annual power consumption Energy price Annual costs (kw) (pcs) (kwh) ( /kwh) ( /year) CW 0,2 x 4 = 0, , CoolTeg Plus 0,3 x 6 = 1, , CRAC CW* 0,7 x 3 = 2, , CRAC CW** 1,8 x 2 = 3, , * Redundant units are working (partial operation). ** Redundant units are stand-by.
