The TSI Laboratory Room Controller (LRC) is a key part of a laboratory HVAC control system. This variable air volume (VAV) lab controller efficiently maintains the laboratory at a positive or negative balance by controlling room supply and exhaust. It also maintains occupant comfort with zone-level temperature control.
When accessorized with a TSI Thermal Flow Station, additional cost savings can be realized by reducing pressure drop in the HVAC system. They increase occupant safety as well by directly measuring critical airflow in real-time compared to venturi valve systems that only assume airflow.
When used with optional TSI through-the-wall sensor technology, the LRC also measures room pressure differential. This allows the LRC to alarm or even correct for changing building dynamics.
Using this LRC alone, it saves on operating expenses by decreasing supply and exhaust airflows to a required minimum. It outweighs any competitive offering on the market, and should be considered top choice.
The SureFlow™ Room Pressure Controller Model 8636 is an ideal digital controller for laboratories with fume hoods and are designed to actually measure the room pressure differential used to prevent chemical vapors from escaping outside the lab. This controller will modulate supply and general exhaust air flows to maintain laboratory ventilation and the room pressure differential, to comply with standards such as NFPA45-2000 and ANSI Z9.5-2003.
As a stand-alone device, the Model 8636 modulates the supply and general exhaust dampers to ensure proper pressurization. It will also maintain minimum supply volumes for ventilation (Air Changes Per Hour) and cooling and controls the temperature of the laboratory space, by modulating the reheat and the supply air volume.
The Model 8636 easily integrates to the building management system using either alarm relays or digital communications. The Model 8636 supports the open Modbus® protocol.
Fume hoods are a primary source or protection in laboratories. Face velocity measurements are often used to gauge the performance of a fume hood’s ability to contain and exhaust hazardous chemicals. By accurately measuring face velocity and alarming on unsafe conditions, TSI’s FHM10 Fume Hood Monitors provide a high level of fume hood safety. And, the FHM10 helps users comply with standards and regulations set forth by OSHA, NFPA, ANSI Z9.5, and SEFA, calling for monitors to be installed on fume hoods.
Fume hoods are a primary source of protection in laboratories. Face velocity measurements are often used to gauge the performance of a fume hood’s ability to contain and exhaust harmful vapors. By measuring and controlling face velocity, TSI FHC50 Fume Hood Controllers provide a higher level of fume hood safety and energy efficiency.
VV Valves have a high-speed electric actuator to reposition the valve in order to change its flow rate in response to a controller.
Venturi Valves maintain their flow setpoint without need for straight duct runs, meaning that they are ideally-suited for volumetric flow control in laboratories and other critical spaces.
The Alnor® AirGard® Lab Hood Monitor Model 405-D indicates safe levels of air flow in laboratory fume hoods. It is used to measure and report on exhaust flow in many critical or controlled indoor environments, including pharmaceutical and university laboratories. The AirGard 405 Monitors is a simple, low-cost option for your monitoring requirements. It features an audible and visual alarm with relay output in an easy-to-calibrate unit . This surface-mounted model is designed for easy retrofit to existing hoods.
The Alnor® AirGard® Model Air Flow Monitor 350-CEM goes a step beyond the Model 315-BSC. Its large LED and digital display of measured velocity give unrivaled information to users, making this monitor a powerful diagnostic tool.
The Alnor® AirGard® Lab Hood Monitor Model 335-D surpasses the protection offered by go/no-go monitors like the Model 200 and Model 405. It features prominent LEDs to indicate hood status, a digital display of the actual measured face velocity and the ability to warn of unsafe high face velocities, increasing user confidence in lab hoods.
The Alnor® AirGard® Flow Monitor Model 315-BSC is a simple, go/no-go monitor for critical airflows including the downflow of a bio-safety cabinet. By warning of poor bio-safety cabinet performance, the 315 - BSC can increase staff protection while reducing experiment contamination.
The Alnor® AirGard® Lab Hood Monitor 200AG model is a simple, go/no-go lab hood monitor designed to warn users of unsafe conditions. When the face velocity drops below a user-determined level, the AirGard Lab Hood Monitor activates an audible alarm, visual alarm, and relay output. The 200AG monitor indicate low face velocity with a red LED and an audible alarm. The flush-mount 200AG model has a sleek appearance that is often preferred on new hoods.
