The TPR-520-1-SD is one of four fan forced premium models of speciality pharmacy/vaccine refrigerators are available up to 1150 Litres to accommodate the requirements of retail pharmacies, medical centres, hospitals and universities where pharmacy/vaccine products are required tobe stored safely. TheTPR-520-1-SD has a capacity of 520 litres and a solid door. Temperature is precisely controlled electronically at +5 C in ambient up to 32 C. The digital display incorporates high (+8 C) andlow (+2 C) temperature alarms, which emit visual and audible signals to warn the operator of an alarm condition. Connectionto a building management system (BMS) has been made easy on the premium range, as they are supplied with voltage freecontacts to allow connection for remote monitoring of power loss, low and high alarms. Cabinet construction is grey Colourbond exterior with interior finish of stainless steel floor and white Colourbond walls. Insulationis high efficiency injected polyurethane foam. All models are available with either glass or solid self closing doors, with key lockson doors for security. A low temperature, protective cut out (LTPC) can be fitted as an optional extra to prevent products inside the refrigerator fromfreezing (particularly important for the storage of vaccines). This independent device will turn off the refrigeration system shouldthe control fail in cooling mode.

  4. The Imperial514 R410Aservice manifold is designed for the professional air conditioning and refrigeration technician, demanding quality and reliability. Suitable for use with R410A refrigerant, the Imperial514 service manifold consists of a colour coded heavy duty, aircraft grade anodisedaluminiumbody, with low and high side gauges, clearly marked in different pressure units, including kPa,PSI and °C for ease of referencing when calculating superheat and subcooling. Each gauge is protected by a colour coded rubber boot (blue for low side and red for high side) and is non-flutter, to make reading accurately easy for the user, as well as a longer life thanks to the reduced vibration. The514 manifold has a needle valve design for full-flow porting to ensure faster charging and evacuation. Ergonomic soft touch and colour coded valves make it simple for the user to operate, even with oily fingers requiring only fingertip pressure to correctly seat, and the dual O-ring design gives the seals trouble free performance and a longer life. The built in swivel hanger allows the manifold to be hung for hands free use. In addition to the three hose ports, the 514 includes a fourth port, giving an additional hook up for using a micron (vacuum) gauge, vacuum pump, adding dye or oil and purging non-condensables. Imperial equipment is manufactured in the USA and is designed for a long and reliable service life. Features: One piece colour coded, heavy duty, aircraft grade, anodised aluminium body Designed for use with R410A refrigerant Pressure scales marked clearly in kPa, PSI and °C Flutter free high visibility gauges for long trouble free service life Colour coded protective rubber boots (red and blue) Dual O-Ring valves with full flow design for faster evacuation and charging Soft seat valves seat tightly with only fingertip pressure Ergonomic colour coded handles give non-slip surface even with oily hands Swivel hanger for hands free use Fourth auxiliary port for hooking

  5. If you are looking for a high quality refrigeration & air conditioning service manifold, then look no further than the Imperial 600 series 4-valve manifold set, whichis designed for the professional air conditioning and refrigeration technician, demanding quality and reliability. The 4-valve configuration, adds a 3/8" vacuum port, and coupled with the oversized internal passages, the Imperial 600 series manifold offers 4-times faster evacuation than conventional manifolds. The area of the 3/8" port, is more than the combined area of the 1/4" low and high side ports of 2-valve manifolds, making evacuation of larger systems much faster and offering a deeper draw. The Imperial 600 series includes a sightglass in the aluminium body, which makes liquid charging and recovery far easier, as the technician is able to see the state of refrigerant through the sightglass. Suitable for R22, R134A and R404A refrigerants, the Imperial 600 series service manifold consists of an anodised aluminium body, which is aircraft grade, with low and high side gauges, clearly marked and colour coded for each refrigerant in different pressure units, including kPa,PSI and °C for ease of referencing when calculating superheat and subcooling. Each gauge is protected by a colour coded rubber boot (blue for low side and red for high side) and is non-flutter, to make reading accurately easy for the user, as well as a longer life thanks to the reduced vibration.

  20. Like all of Fieldpiece's test instruments, the SRL2 Infrared Refrigerant Leak Detector is designed exclusively to make the HVACR Technician's job easier, faster, safer and more efficient. Fieldpiece set out to develop the best refrigerant leak detector for HVACR and now it comes in kit form in a rugged, blow-moulded case with all of the extras (see What's Included). The ergonomic design fits naturally in your hand. The ruggedized construction stands up to abuse most other leak detectors can't handle. The eight-hour battery life lets you work all day before recharging and the included vehicle and wall chargers help you during overtime. The mute and peak functions allow you to work the way you want to work. The magnetic hanger helps keep the detector out of the way when repairing a leak, but visible enough so you won't leave it on the job. The SRL2 triggers on a change in refrigerant levels as refrigerant passes by the sensor. Infrared (or IR) sensors work on the principle that refrigerants reflect a certain spectrum of light that is “below red” or infrared. When refrigerant is drawn into the sensor, it travels between a light/heat source and a sensor that is constantly receiving a “picture” of that light. Like a cloud that reflects solar radiation and “blocks” out the sun, the refrigerant reflects the infrared radiation and blocks the sensor from receiving the complete picture. The result is a trigger. However, after the “picture” stays the same for a while, the sensor no longer senses a change and the triggering stops. This is important. IR sensors act almost exactly like the motion sensors that trigger your neighbor’s blinding garage lights outside. The outside sensors are taking a picture of a designated area. When someone walks into that picture a change is detected. The light turns on. If you stand in the same place without moving, eventually the light turns off until you move again. Becau
