Recirculating chiller DL30-1000CE

Recirculating Chiller DL30-1000CE Overview

The Recirculating chiller DL30-1000CE is a closed-loop cooling system designed to provide a constant low-temperature environment for chemical, biological and physical experiments that must be carried out at reduced temperatures. With a cooling capacity of 1000 W and a minimum no-load temperature of -30 °C, it delivers steady refrigeration across a working range from -30 °C to approximately 5 °C. The unit is widely used in medicine and healthcare, the food industry, the chemical industry, and for educational purposes in research institutes.

Circulation is handled by an integrated pump rated at 20 l/min with a pump pressure of 0.4 bar, feeding a 30-liter tank. The completely closed circulation system helps prevent evaporation or contamination of the liquid in the bath, while the temperature stability of ±2 °C supports applications such as fermentation processes and vessels for chemical synthesis. The chiller can serve as a reliable thermal control source for laboratory setups, including pairing with high-capacity high-capacity rotary evaporators that require sustained cooling of condensers.

Design and Advantages

The DL30-1000CE is built around a world-famous brand compressor that contributes to low noise, high reliability, stable operation and a long service life. It uses an eco-friendly refrigerant without freon that complies with international standards. Built-in filters in the hoses help prevent clogging, and a liquid level indicator allows the remaining bath liquid to be monitored at a glance. Removable side panels make cleaning and routine maintenance quick and straightforward, and the compact design keeps the footprint manageable on a laboratory bench or floor.

• Suitable as a fermenter or vessel support for chemical synthesis
• Closed circulation prevents evaporation and contamination
• Hose filters reduce the risk of blockages
• Liquid level indicator for easy monitoring
• Removable side panels for accessible servicing

Selecting the Right Model

The DL30-1000CE is part of the DL series, which includes several models with differing capacities held in our warehouse. Laboratories needing a smaller cooling output within the same series may consider the DL30-700CE, while applications with different temperature or capacity requirements can also be served by the recirculating chiller DLSB-5/20A. The unique specifications of each model are listed in the individual specification tables, as well as in the visual comparison table covering all four chillers of the DL series.
