Chilling Without an Integral Sump
If the plant already has chilled water storage, an integral sump is a tank you are buying twice. Tankless models drop it, keeping the evaporator and the enclosure and shrinking the footprint accordingly.
A tankless falling film chiller keeps the enclosed cabinet and the Temp-Plate evaporator plates but omits the collection tank. Chilled water leaves the unit directly into an existing sump, storage tank or process loop.
When it makes sense. Where a chilled water tank already exists, where the process itself provides the buffer volume, or where floor space is tight enough that the tank is the binding constraint on installation.
What you have to provide. Buffer volume somewhere. The refrigeration system needs thermal mass to avoid short cycling, and without an integral tank that mass has to come from the storage or the process loop. Say what you have and the control arrangement is designed around it.
Available in both plate formats. Tankless configurations are offered with 3x5 and 4x8 evaporators, so the capacity range is the same as the tanked units.

Tankless Falling Film Chillers
Thermal Mass Is the Design Question
Refrigeration systems need somewhere to put capacity when demand drops, or they short cycle and wear. An integral tank provides that; without one, the storage or the process loop must.
Tell us the volume and temperature of what the chiller discharges into, and the control arrangement follows. This is the item most often overlooked when a tankless unit is specified purely on footprint.
Questions on fit
Enough that the refrigeration system can run long cycles when demand drops, without the leaving water swinging. The exact volume depends on the refrigeration capacity and how the load changes over the day. Give us the size of the existing tank or loop and its normal temperture, and the controls are set around it.
Where the hydrocooler reservoir sits below the chiller outlet and holds enough water, it can act as the storage. Check the elevation so chilled water reaches the reservoir by gravity without backing up into the cabinet. The hydrocooler pump then becomes the circulating pump for the whole loop.
Good insulation, a sound cover and a return pump sized to deliver water to the chiller distribution pan at the flow the plates need. A tank that has lived with a warmer process may also need its own outlet moved so chilled water is not drawn off before it mixes. Photos and a sketch of the tank help.
Tankless units are built with 3x5 and 4x8 evaporator plates, so the capacity choices match the tanked range. The decision on format is made exactly as it would be for a tanked cabinet, based on capacity and room. Only the sump is missing, and the floor space it would have taken comes back.
The chiller cabinet is cleaned the same way, but the storage hygiene now sits with your existing tank. If that tank is open, older or hard to drain, it becomes the weak point in the chilled water system. Bring it into the same cleaning schedule as the chiller.
