SP Industries has announced that its Virtis Genesis 25 and 35 XL freeze-drying systems, which now feature proprietary auto-cascade refrigeration technology, can achieve low freeze-drying temperatures.
The systems achieve these low temperatures while reducing operational energy consumption by 30 per cent to 40 per cent compared to two compressor cascade systems, according to the company.
A single 1.5hp compressor powers the environmentally friendly refrigeration system.
These units can achieve -60C shelf temperatures and -70C condenser temperatures while still providing the solid uniformity of drying conditions.
Virtis Genesis freeze-drying systems facilitate scale-up from research through to pilot-plant production.
The compact, freestanding, mobile design enables the system to be configured to almost any freeze-drying application.
Ergonomic profiling eases inspection of the vacuum pump and facilitates oil changes.
The product chamber, shelves and condenser chamber are made of durable 316 L stainless steel, with a squared product chamber that ensures easy cleaning and maximum shelf area, according to SP.
A 4in-diameter port increases vapour flow from the product to the condenser chamber, maximising system productivity.
CFC-free refrigeration systems allow the Genesis range to achieve a range of temperatures, enabling the freeze drying of all sample types.
Multiple-stage freezing and drying steps can be programmed.
