Door latch includes key lock and provision for padlock. Standard on all Advantage and Basic upright models. Advantage upright freezers are available in four sizes. Shown with chart recorder. Pressure Equalization Port Advantage chest freezers feature low profile designs for easy access. Shown with chart recorder. Pressure equalization port controls amount of atmospheric air allowed into the storage chamber after door openings. Standard on all Advantage and Basic upright freezers. Combats vacuum created by pressure differential upon door closing. Allows cabinet re-entry within 30 seconds of door closing. Microprocessor Controls The Advantage microprocessor controller delivers information on available line voltage, battery reserve and charging capacity, setpoints, airflow across the filter and more. Internal probes and sensors accumulate and compare numbers on temperatures, pressures, voltage and amperage. An RS-232 data port includes software to log information onto a PC.

Silent witness alert supervises freezer operation, scans data points from internal and ambient sources, and warns of both current problems and problems which have occurred and self-corrected while the freezer was unattended. Alarm Function Touchpad controls are tamper-resistant. A SELECT mode allows easy programming of setpoint. Built-in voltage boost system helps protect refrigeration components by automatically compensating for insufficient line voltage. Alarm/Monitor System The built-in safety alarm system has an automatic, continuous charging battery backup to provide full function performance in case of a power failure. Tamper-proof key switch locks alarm in ON or OFF mode. Independent high and low alarm setpoints are adjustable in 1 C increments. Alarm activates an audible and visual warning on power failure or temperature deviation. If the freezer is in alarm (warm, cold, low voltage, power failure) If the problem has corrected itself In a temperature deviation When the alarm reset button is pressed the warning light flashes quickly; temperature display also flashes during a power failure. the warning light flashes slowly. A self-corrected temperature alarm alternates flashing between the temperature failure alarm and warm or cold alarm. the silent witness alert holds the warmest temperature in memory, ready for recall by simultaneously pressing the cabinet temperature and warm alarm setpoint buttons. the slow flash is stopped and the memory is cleared for continuous monitoring. Touchpad controls are tamper-proof. Large-scale,easy-to-read LED display provides direct readout of operating temperature, setpoint, high and low alarm parameters, plus line voltage and % battery capacity. Indicator lights show status of all operating systems. Clean filter indicator light reminds you to wash filter to protect condenser from dust buildup; no tools required. Single key switch controls main power and alarm ON/OFF functions. Push-button alarm test physically warms probe to simulate an actual alarm condition; no door or lid opening is required. Data entry pads for operating temperature, overtemperature and undertemperature parameters. Low battery indicator advises when to replace long-life, self-charging alarm system battery. Push-button displays % battery capacity on digital readout. Low voltage alert warns of low voltage; push-button displays line voltage on digital readout. A voltage booster will protect refrigeration system during brown-out periods. 3
Basic Ultra-Low Freezers Queue Basic ultra-low freezers are designed for-86 C storage, processing and testing. The Basic solid-state electronic control system allows simple, accurate control with a pre-set alarm. Basic Solid-State Electronic Control System The Basic control panel is designed primarily for temperature setpoint and display with the added advantage of a pre-set alarm. Overtemperature alarm with audible warning is factory pre-set at 90% of selected operating temperature setpoint. Key-operated on/off switch controls main power; the freezer cannot be turned off unless the key is inserted. Temperature control adjustment is recessed to prevent tampering. Large, easy-to-read digital display indicates both setpoint and actual temperature at the push of a button. Built-in voltage boost system helps protect refrigeration components by automatically compensating for insufficient line voltage. Simplified controls include a key-operated on/off switch and bright LED temperature display. Cascade Refrigeration System Air-cooled refrigeration systems feature CFC-free refrigerants and are engineered to maintain design temperatures in 32 C ambient setting. The -86 C refrigeration system includes two 1 HP compressors; -50 C and -40 C models use a single compressor. A washable condenser intake filter maintains peak operating efficiency. The filter is easy to clean; no tools are required for removal. A noise suppression design minimizes normal operating sound. Chest Models The low profile chest design provides easier access to the inventory system. The fully insulated, counterbalanced lid with keyed lid lock improves security (key lock not available on 90 liter model, padlock provision provided). Independent, double-seal gaskets with sub-lids reduce frost buildup and provide additional protection. A full length lid handle is. Model QBF-1385, Basic -86 C Upright Freezer, 379 liter capacity Model QBF-1490, -86 C Chest Freezer, 388 liter capacity General Cabinet Design, and Basic Series Upright Models Space-saving upright cabinets are available in four sizes for most efficient use of floor space. Low height cabinets (197 cm including casters) allow for easy installation and movement of freezer through doors, hallways and lifts. The insulated outer door with keyed lock forms a positive seal for added inventory security (2 keys provided). Integrated door and latch assembly allows for easy right-or left-hand operation. Padlock provision is on all upright models. Five insulated inner doors minimize cold air loss during door openings. Four stainless steel interior shelves make efficient use of interior space (three are adjustable, one is fixed). Cabinet Construction Chest and upright cabinets are insulated with a minimum of 12.5 cm foamed-in-place urethane insulation to protect the stored product from high ambient temperatures. The 100% steel cabinet includes a high-impact epoxy finish for easy cleaning. A 25 mm diameter access port is pre-positioned in each cabinet. High-strength casters are included for easy installation. 4
