Tenney BTRC Benchmaster Environmental Temperature & Humidity Chamber Comes with what you see in the pictures. If you don't see it, you probably wont get it. Specifications are from Tenney/Lunaire and may vary slightly due to upgrades, options, or revisions this unit may or may not have. The chamber is guaranteed to work. The Unit's Serial Number Tag Reads: Model Number: BTRC Serial Number: 26776-07 Type of Refrigerant #1: R-404A Charge Weight Avoir.: 30 oz. Type of Refrigerant #1: R-23 Static Charge @ 75°F: 85 PSI Main Power Requirements: 208 V, 1 Phase, 60 Hz, 23 Amps, 30 Amps Fuse Additional Information: 1 shelf included Chamber Light Dry Air Purge 4" and 1" Feedthrough/Access Port on the side VersaTenn III Digital Programmable Controller IEEE/488 Interface Viewing Window Humidity Capability of 20 to 98% RH General Description: These well-received test chambers are capable of simulating a wide range of temperature and humidity conditions. The Tenney Benchmaster chambers provide a workspace of five cubic feet, readily accommodating equipment as large as a 19" relay rack. These cambers are ideally suited for electronic, military, and pharmaceutical quality assurance and reliability testing, as well as research testing and production processes. As specified, the chambers are mechanically refrigerated by means of a single system of time-proven design. All humidified models are equipped for total programming capabilities of temperature and humidity over time. The VersaTenn control is a proprietary instrument developed specifically for environmental chambers, thus it is easy to use and precisely designed to take complete command of the chamber's conditioning system. Construction: The chamber features a vapor-tight interior liner made of 100% stainless steel that is continuously welded under inert gas. Reinforcement is use at all critical points, and through-wall ports are continuously welded. The workspace is fully insulated with a combination of fiberglass and polyurethane that optimizes that insulating characteristics of each material. Control System: Proprietary VersaTenn provides fully automatic, PID, chamber control through a user-friendly alpha-numeric display. The control is bi-directional, proportional heating, cooling, humidification, and dehumidification. The proportional band and the reset are operator-adjustable. Logic circuits automatically select cooling, heating, and humidify modes are required. 99 step programming capability with step-interval length of 99 hours. Ability to store up to 10 resident programs. Looping and nested-loop capability. Loops can be repeated up to 255 times. Infinite looping is possible. Time intervals are programmable in seconds, minutes, and hours. Time-of-day start and delayed start functions up to two weeks. Non-volatile memory for up to 5 years of power-off protection of RAM. Digital selection and indication of actual conditions. Temperature is measured and displayed in °C or °F, and humidity in %RH. Sensors: A platinum RTD sensor measures temperature. Humidity is measured by an electronic, capacitive sensor that requires no wet wick or water supply. The sensors provide excellent control and display accuracy with minimum tolerance. Refrigeration System: The Tenney Hermeticool is an Air-cooled, readily accessible hermetic system that uses accurately calibrated capability capillary tubes rather than mechanical expansion valves. This simplifies the system and reduces the likelihood of leaks. Sequential starting of compressors in cascade system substantially reduces starting current demand. Humidity System: The Tenney VaporFlo is a humidity system constructed of 100% non-corroding parts and is equipped with its own low-water protection system. A transparent Pyrex vessel permits easy inspection (not included) and affords easy clean out and maintenance. The system operates at atmospheric pressure and is specifically vented to prevent unwanted siphoning. Heating System: Low-mass nichrome, open wire heating elements are used to reduce thermal lag and provide rapid response to instrument demand. The heating elements are isolated from the workspace to reduce radiant influence on the test item. Electrical: All wiring complies with NEC. Electrical components are located in a readily accessible, integral control panel. For installation convenience, a six foot electrical cord and matched plug, receptacle, and cover plate are supplied with all units. Conditioning System: Uniform conditions are assured through the use of a vertical-down recirculating conditioning stream. The system draws air through the bottom of the workspace, conditions it as required, and discharges it through a grille at the ceiling level. The compact design of the conditioning plenum allows the test chambers to offer a larger proportional area of interior volume to exterior volume than afforded by conventional chambers. Door: Because the chamber liner is sealed by continuous welding, the door remains as the final sealing surface. All doors are equipped with double gaskets that trap air for the purpose of insulation, as well as atmosphere integrity. A unique, energy-efficient system circulates hot gas from the refrigeration system to provide automatic defrost for the door gaskets. This both extends gasket life and assures pliable gasket conditions.
