Drying – Drying Ovens

MARC has been manufacturing large capacity high-performance Industrial DO1, DO2 and DO4 trolley drying ovens for decades. Our DO1, DO2 and DO4 trolley drying ovens have an exceptionally long life expectancy that spans decades. 

1. Large Capacity Trolley-Ovens 

Even heat distribution is notoriously difficult to achieve in large ovens – but our oven range has always been the market leader in that regard. We paused the manufacturing of our flagship large-capacity trolley-oven range to spend a significant amount of time engineering in even better heat distribution – and now we can offer a leap forward in performance improvement.   

We are now pleased to announce the release of our new-generation DO2E-HP. 

MARC DO2E-HP

Re-designed from the ground up our flagship DO2E oven now includes performance improvements in:

1. Air Flow – A larger Volume Direct-Drive Fan;
2. Air Distribution – A High-Performance Slotted Air Distribution System;
3. Graphical Temperature Display; 
4. Insulation – Two Stages of Insulation dramatically Improves Heat Retention; 
5. Drip-Free Exhaust Management – i.e. Condensing Steam doesn’t Run back into the Oven; 
6. Stainless Steel Load-Rated Trolley Design – Our Standard Oven Trolley is Now Independently Load Rated to 900 kg;
7. Upgrade Options:
   • Relative Humidity Probe – View a Graphical Display of the RH over Time – know when your samples are dry.
   • Auto-Purge Control – When used with the Relative Humidity Probe the Oven will Purge Moist Air at a Pre-Set Internal Humidity Limit. At 105 °C the benefit of this is limited and will primarily aid in steam, smell or noxious off-gas removal but for lower temperature drying this can reduce drying time by up to 23%.

2. Portable Large Capacity Rack-Ovens 

Larger capacity drying ovens than the DO2 size are even more notorius for heat distribution problems. Typically they are simply extended DO2 ovens with the same electrical compononents and fans despite containing double the sample volume and therefore (potentially) double the moisture volume.  

Our DO4 (4 x 1m³ trolleys) oven – like our DO2 – has been redesigned from the ground up. The sample drying capacity increases from 4 x 1m³ to 4 x 1.2m³ but in stackable racks and not trolleys.  Stacked sample racks are removed from the oven with a forklift and placed on dollys or on battery operated lift-tables for relocation. 

Due to the physical size of this oven it is not available for export but it is relocatable and is designed to sit out in the elements so does not need a cover.

3. Smaller Capacity Floor- or Bench-Mounted Drying Ovens

We also supply smaller bench-mounted and intermediate floor-standing ovens. These  can reach temperatures of up to 250°C.
