Energy efficient drying ovens with maximum durability

Our Essa® RD10HMI Infrared Drying Oven is a fast-acting tray drying oven suited to drying samples that weigh up to 8kg. It simultaneously uses two innovative heating mechanisms to ensure quick drying – overhead infrared heat lamps and a hotplate which heats the sample from underneath.

An HMI colour touchscreen, which displays set-point and actual values, is easy for operators to use and allows precise machine control. A pyrometer monitors the infrared heat lamp operating temperature and a contactless sensor and dimmer allows effortless control of the heat lamp temperature. A thermocouple measures the hotplate temperature from below. 

A truly intelligent tray dryer, our Essa RD20HMI Infrared Drying Oven and Moisture Determination delivers the advantage of efficient wet sample drying coupled with the simultaneous monitoring of moisture loss. Advanced temperature monitoring provides the flexibility to pre-set temperatures and the surface temperature of the sample to be measured and accurately maintained. An internal load cell allows the continual monitoring of moisture loss while the sample is drying, further adding to the precision of the sample drying process.

Additionally, with its HMI functionality, it is very easy to operate and offers very precise control. This brings many advantages, including faster and more energy efficient drying and better drying results.

Our Essa® RD20HMI Infrared Drying Oven and Moisture Determination is suited to samples weighing up to 8kg and can be operated in two modes:

•    Set time – benefit from complete control over the drying cycle by specifying the drying time, between 1 and 300 minutes.

•    Auto stop – use the oven’s intelligence to determine when the sample is dry. The technology compares the sample’s current mass measurement to its mass measurement at the time it was placed in the dryer. All your operator needs to do is specify the minimum weight change, number of “no change” readings, and the re-weighing period.

Adding to the oven’s adaptability and appeal, a version for use in robot circles is also available, with the touch screen panel and electrics housed in a separate electrical cabinet which is mounted outside the robot enclosure.

Our Essa® RD20XL Infrared Drying Oven and Moisture Determination is identical in every way to the RD20HMI except it is suited to even larger samples.

Its extra-large sample size capacity improves productivity as it removes the need for further stages of sample size reduction prior to samples entering the drying process. 

Our Essa® RD51 Infrared Rotary Dryer offers the advantage of quick and even faster drying. Its drum design means the sample is always on the move and the sample’s exposed surface is continually changing. This results in a more constant heat profile through the sample and significantly faster drying.

Like all dryers in our RD series, our Essa® RD51 Infrared Rotary Dryer uses an innovative temperature-controlled infrared heating head. Heat is efficiently transferred directly from the head to the sample – energy is not wasted heating the ambient space around the sample.

The dryer is best suited to drying samples weighing approximately 15kg. A user-friendly interface ensures accurate operator control and complete precision when it comes to setting drying times.

The dryer can be used manually or incorporated into an automated drying system – this adaptability further adds to its value in your setting.
