SPENCERS shelf
freeze dryers provides the maximum shelf space possible for phase
one research to clinical production and small volume production. The
shelf chamber is designed to meet end user requirements with
optional heating system as per requirement.
CAPACITY OPTIONS
Shelf freeze dryers with
various capacity options from 3 litre upto 100 litres.
OUTER BODY
Outer of the cabinet is made
of Galvanized Sheet of suitable thickness & grade finished with
bacteria resistant coating.
CONDENSER CHAMBER
Stainless Steel condenser
chamber. The
corrosion resistant stainless steel condenser chamber is thermally
insulated and acts as a trap for water or other solvent vapour.
WORK SURFACE
The top work surface is made
of polished stainless steel.
INSULATION
Safe, high density,
non-settling &Thick polyurethane insulation .
SHELF CONSTRUCTION
All internal surfaces are
constructed of 316L stainless steel and offer a polish of 20 Ra or
better. The shelves are constructed as per the required capacity and
the required gaps between the shelves.
FRONT & SIDE PANEL
Convenient, accessible & easily removable front
and side panel allows access to refrigeration system & vacuum
system.
CASTORS
Castors are provided for
minimal effort mobility.
MANIFOLD SELECTIONS
Manifolds are available in a
wide selection of shapes and sizes. Generally Permanently installed, drying chamber has 1/2" and 3/4" ports
to accomodate flasks. These ports/valves can be used for attaching a
variety of sample containers such as flasks, vials or ampoules.
STOPPERING SYSTEM
Convenient sealing/stoppering
device with either bulk or bottom-up hydraulic stoppering
configuration. Both options have a radiant heat plate above the top
shelf for uniform drying on all shelves.
Refrigeration:
Strong and reliable with powerful
quick response refrigeration, an exclusive long life SPENCERS
superior refrigeration process is an unique feature of SPENCERS
Freeze dryers. High capacity refrigeration system ensures rapid
cooling. The refrigeration system is designed as per customer
requirements.
A large flange opening enables easy inspection,
cleaning and water defrosting. Retractable Drain hose are easily accessible for
convenient service. The chamber is connected to a valve drain at the
front of the unit for simple and quick removal of condensate. Condensation trap
is made of
stainless steel.
Clear lid provides view if ice build-up.
To facilitate defrosting, a retractable condensate drain line is
easily accessible through the back of the cabinet.
TEMPERATURE
RANGE
-30 °C, -40 °C, -55 °C, -60
°C, -80 °C, -86 °C etc.
TEMPERATURE CONTROL
Micro-controller /
Micro-processor based controls.
TEMPERATURE DISPLAY
Digital LED/LCD display.
COMPRESSOR
Hermetic type sealed Heavy duty
Air-cooled Compressor matched to a system fitted with oil separator,
suction accumulator, filters, and all necessary safety devices for
correct operation. The compressor is distinguished by its excellent
performance, low noise level and minimal vibration.
REFRIGERANT
Non-CFC/HCFC environmental friendly refrigerant based on
compressor capacity.
Condenser System:
Highly efficient condenser.
The Freeze Dryer has the ice vapour condenser
located beneath the product section within the same chamber. This
arrangement allows the shortest distance of unrestricted travel for
the transfer of vapour. The corrosion resistant stainless steel
condenser chamber is thermally insulated and acts as a trap for
water or other solvent vapour. A large flange opening enables easy
inspection, cleaning and water defrosting. The chamber is connected
to a valve drain at the front of the unit for simple and quick
removal of condensate.
Vacuum System:
Dual stage, belt-driven, high
vacuum pump.
Vacuum drum is made of stainless steel.
Vacuum pump draws moisture from sample into the freeze dry chamber.
An azide proof vacuum pipeline connects the chamber to a 16mm O.D.
tube on the front panel, to which suitable 2-stage oil sealed rotary
vacuum pump accessory may be connected. The pumping line has a
separate isolation valve. . Individual guages monitor vacuum.
