Recirculating chillers are quoted against cooling capacity at the working temperature — capacity falls as the set point drops, so the pairing guide matters. This page lists what to confirm before ordering. or the chiller sizing guide with measured capacity tables
What to Confirm Before Ordering
Documentation: Specify any required certification or conformity documents in your inquiry. Their availability must be confirmed for the quoted configuration. No CE declaration or certificate number is published on this page.
Site requirements: State your cooling-water, vacuum and electrical requirements, and identify any supporting equipment required in the quotation.
What to Tell Us for an Accurate Quote
| Item | What to state |
|---|---|
| Model and series | DLSB sealed and non-sealed models across 5–100 L; state the model or the capacity band you need. |
| Capacity at working temperature | Each model lists cooling capacity at room temperature, 0 °C and its lowest point — compare the figure at your working temperature. |
| Lowest-point figures | Some lowest-temperature capacity figures in the −30 °C and −40 °C series remain to be confirmed. Request the confirmed value for the selected model and configuration. |
| Pump and reservoir | Confirm pump and reservoir specifications for the selected model. |
| Temperature range | −30 °C or −40 °C series per model; state your lowest working temperature. |
| Power supply | State your site voltage and frequency. |
Send these with your inquiry through the contact page; the more complete the list, the closer the first quote lands.
Procurement Questions
What is the difference between sealed and non-sealed DLSB models?
