WTS-100-2

Tank control unit with cleaning function


 

Combined cleaning and milk cooling control -super flat-
with connection possibilities for milking robots

 

The WTS-100-2 is a combined cooling and cleaning control unit for closed milk-cooling tanks.

It offers a top-quality milk cooling regulator which controls the agitator and compressor / evaporator valves. Other features include an adjustable cooling start delay and cooling time monitoring for the first milking, together with automatic after-stirring and press-button switching between target temperatures.
The complete cleaning timer controlling water valves, washing pump, heater, outlet valve etc. offers a full range of adjustable parameters. The cleaning programme is flexible and comprises up to six separate rinses, each of which can be repeated several times. If only one main wash per cleaning programme is chosen, there is an additional option to determine how many times cleaning should take place with alkaline detergent before the tank is cleaned with acidic detergent.

Water intake is by level or by time, as preferred. Outlet valves can be programmed to be “de-energised open” or “de‑energised closed”.

During cleaning a connected robot is switched off by the WTS-100-2's “Cleaning active” signal. After cleaning, the robot restarts the cooling process via a digital input signal.

 


Also completely in the control box:
Perfect for the retrofitting of existing systems!

The universal cooling-tank control unit is also available pre-installed in a sturdy switchbox (IP65) for wall mounting. All necessary contactors for washing pump and heater are already built in and fully wired.

All consumers are connected directly via terminals.
