Percival’s IntellusUltra Controller
-Percival Scientific has built a reputation of providing flexible, customized options for research scientists around the world. We have taken the philosophy to the next level with our improved IntellusUltra controller. Now choose from the levels of functionality that meet your research needs.

Lighting System
-Each tier of shelves is lighted by fluorescent lamps properly spaced for uniform light intensity over entire shelf
-Intensity programmable up to 405 micromoles./m2/sec of light irradiance measured at 6” from lamps on 2 on/off light events
-Two levels of programming of fluorescent lighting
-Programming and control of the lighting is done via IntellusUltra real time controller

-Uniform air circulation across each shelf via air diffusers on the rear wall

Cabinet Construction
-Interior constructed of 22-gauge electro-zinc plated steel
-Exterior constructed of 18-gauge exterior electro-zinc plated steel
-Welded seams and joints on outer and inner shells
-Inner shell supported by non-compressing/non-thermal conducting material locking inner liner in place without a metal-to-metal bond to outer case
-Chamber is completely self-contained
-Overall wall thickness is 2”
-One 1 1/2” diameter access port on R.H. wall
-Stainless steel chamber floor equipped with floor drain and hose assembly
-Contains caster assembly and adjustable leveling legs to compensate for floor unevenness in the lab

-Woodless construction using CFC free insulation (overall wall thickness is 2”, ample insulation for maintenance of stated temperature range)

-One door opening of 36.8” x 57.5” providing full access to chamber interior (magnetic gasket provides a tight seal to door frame)

Interior Space
-37.2 cu.ft. with work area of 27.2 sq.ft. provided on four shelves

-Four tiers of white epoxy coated steel wire shelving (each shelf is 27”D x 36.3”W)
-Shelves are vertically adjustable in 1/2” increments
-Maximum growing height is 10.6” per tier with all four shelves installed

-Interior and exterior painted with high reflective, environmentally friendly, high temperature baked white powder coating

-Self-contained air-cooled condensing unit with hot gas bypass system for continuous compressor operation, extended life and close temperature control (this continuous running condensing unit ensures precise temperature control by alternately cycling refrigerant and hot gas to coil; this also prolongs life of compressor, and eliminates risk of ice build up in coil)
-Solenoid valves have extended stem for quiet and long life operation
-Ceiling mounted evaporator coils incorporate twin air circulation fans in aluminum housing (heat rejection to ambient in standard chamber = 4500 BTU/hr)

Temperature Range
– 7-44C (+/- 0.5C) with lights on and 2-44C (+/- 0.5C) with lights off

Temperature Safety Limit Controls
-Experiment Protection: Adjustable high and low temperature controls, audible alarms, and visual indicators provided
-Controls shut down all power to chamber, activating alarms (when the temperature returns to the normal range the system will automatically reset)

Convenience Receptacles
-Two 115/1/60 convenience receptacles provided inside chamber
