Drive Frame Size

Supply Loop Requirements

(1)

Supply loop requirements are for the input to the heat exchanger. These are not requirements for the drive. The output of the heat exchanger is designed to meet the flow and

pressure requirements of the drive. For the flow and pressure requirements of the drive, see the table on page 46

Liquid-to-Liquid Heat

Exchanger Cat. No.

(3)

Recommended cooling loops shown are based on a single drive per cooling loop. Consult the factory for use of multiple drives on one cooling loop.

Minimum Flow @ Pressure

(2)

The minimum pressure applies to the pressure drop across the heat exchanger and does not take into account additional pressure drop in the system such as piping or hosing.

Maximum Pressure Temperature Range

2 15.1 LPM @ 0.83 bar (4 GPM @ 12 PSI) 8.62 bar (125 PSI) 0-40°C (32-104°F) 20L-LL13K-P75A

3A 22.7 LPM @ 0.83 bar (6 GPM @ 12 PSI) 8.62 bar (125 PSI) 0-35°C (32-95°F) 20L-LL13K-P75A

3B 56.8 LPM @ 0.83 bar (15 GPM @ 12 PSI) 8.62 bar (125 PSi) 0-35°C (32-95°F) 20L-LL24K-1P0A

Drive Frame Size Estimated Amount of Coolant

(1)

The estimated amount of coolant is based on the heat exchanger using 1.2 m

(4 ft.) hoses. Longer hoses require more coolant. The maximum hose length

of 9.1 m (30 ft.) would require up to an additional 2.8 liters (3/4 gal.).

2 15.1 liters (4 gal.)

3A 19 liters (5 gal.)

3B 19 liters (5 gal.)

Each hose kit contains two (2) hoses and the appropriate connectors.

When a chiller or liquid-to-air heat exchanger is preferred, we recommend consulting with a cooling

loop supplier such as Dimplex Thermal Solutions. The following are recommended chillers.
