Versatile Wilo Recirculating Pump Wilo-TOP-S For Air Conditioning And Cooling Systems

Glandless circulator with screwed connection or flange connection.

Hot-water heating systems of all kinds, industrial circulation systems, air-conditioning systems and closed cooling circuits

Operating modes

• Speed-stage switching

Manual functions

• Setting the speed stages: 3 speed stages (2 speed stages for 1~ pumps with P2 ≥ 350 W)

Automatic functions

• Internal protection against non-approved high winding temperatures (only for pumps for which P2 ≤180 W)

Signal and display functions

• Thermal winding contact (WSK, potential-free NC contact) only for pumps for which P2 ≥180 W) for full motor protection in all speed levels with optional tripping unit SK 602N/SK 622N
• Direction of rotation control light (only for 3~pumps )
• Display of selected speed stage

Dual pump management (double pump or 2 x single pumps)

• Main/standby operation or parallel operation (for automatic fault-actuated switchover/time-dependent pump cycling, a corresponding switchgear must be provided on-site)
