Product Description
Feeding a condenser from the tap wastes water continuously, gives you whatever temperature the building supply happens to be that day, and in many places is no longer permitted. A closed recirculating chiller fixes all three: the same charge of water circulates at a set point you choose, and nothing goes down the drain.
The CF-802A solves a different problem: one chiller, up to four rotary evaporators. With a 16 L reservoir and the cooling capacity to match, a teaching laboratory or a shared prep room can run a bank of evaporators from a single unit instead of buying four chillers, four power circuits and four footprints. The saving is in capital and in running cost at the same time.
Key Features
- Runs up to four rotary evaporators from one unit
- 16 L closed cooling system
- −20 °C to room temperature
- Magnetic drive pump — no shaft seal, so nothing to leak or replace
- Waterproof touch panel with a large LED display and sheet keys
- Heat-resistant fixed lid — less energy used and less cooling capacity lost
- Water saving closed-loop design
- Non-CFC R404A refrigerant, 300 g charge
- Stainless steel coolant reservoir, stainless and resin cover

Choosing Between Them
| Model | Capacity | Temperature range | Best for |
|---|---|---|---|
| CF-303Y (115 V) / CF-313Y (220 V) | 3.9 L | −20 to 30 °C | One rotary evaporator, limited bench space |
| CF-802A-115V | 16 L | −20 °C to RT | Up to four rotary evaporators from one chiller |
| CB-100-115V / 220V | 3.4 L | −10 to 80 °C | Work that needs heating as well as cooling |
The deciding question is usually not capacity but whether you ever need to go above ambient. If you do, the CB-100 is the only one in this range that will do it. If you only ever need to remove heat, a CF costs less and is purpose-built for it.
Installation Requirements
- Electrical: AC 115 V.
- Ventilation: a chiller rejects the heat it removes into the room. Leave clearance around the air intake and exhaust, and do not box it into a cabinet.
- Coolant: use clean water or a water/glycol mix appropriate to your lowest set point — below 0 °C a glycol mix is required. Tap water left standing in a reservoir grows biofilm; plan on periodic changes.
- Hoses: insulated tubing sized to your instrument, not supplied.
- Multi-instrument use: connecting four evaporators means four hose runs — plan the bench layout before ordering.
