Thoren Caging Systems, Inc., is a pioneer and worldwide leader of innovative caging systems for the laboratory animal industry. Thoren was the first to develop warm surface plastic caging in 1953, and in 1978, in conjunction with The Jackson Laboratory, Thoren brought Positive Individual Ventilation (PIV) to the forefront of the industry with the introduction of the Maxi-Miser PIV Caging System. Today, PIV technology is an established industry standard.

For over 40 years, Thoren Caging Systems' total commitment to high quality product design and customer satisfaction has earned us a place in the top research facilities throughout the world. Thoren products meet "The Guide for The Care and Use of Laboratory Animals" as established by The Institute of Laboratory Animal Resources.

Thoren's Maxi-Miser PIV Caging System supplies Positive Individual Ventilation to each cage position. The system provides approximately one cage exchange of air per minute (depending upon static pressures), supplying air directly into each cage while exhausting spent air, animal odors, dander and feed dust from the cage. Maxi-Miser minimizes problems associated with the buildup of temperature, humidity, carbon dioxide and ammonia. Thoren's PIV technology also gives welcome relief to allergy sensitive staff members by reducing cage contamination in the room.

The Maxi-Miser PIV System has been designed to operate efficiently from either the laboratory central ventilating system or through Thoren's Blower Filter Modules. These easily detachable, self-contained Blower Filter Modules feature 99.99% efficient HEPA filters and contain dampers on both the supply and exhaust systems. Maxi-Miser Blower Filter Modules are available in bottom mount or top mount positions. Each 120 volt, single-phase 60 hertz unit draws 4 amperes at full load. (240 volt, 50 hertz available upon request.)

Modular in design, the Maxi-Miser System can be constructed as a fixed or mobile unit using four basic cage designs: Small Mouse - Rat - Weaning - or Duplex. All units are available with automatic watering systems, bottle watering or combination of the two.

The Maxi-Miser Mobile PIV Caging System consists of the stainless steel rack with air plenum and hollow, three compartment, stainless steel shelves. The unit provides positive or negative cage pressure relative to the room, and is equipped with separate Magnehelic gauges to monitor static pressure on both supply and exhaust. Stainless steel construction and easily detached Magnehelic gauges allow the system to be fully washed and autoclaved. Quick disconnect clamps provide easy removal of both shelves and plenum plates prior to cleaning. Blower Filter Modules are also autoclavable, having been designed with detachable electrical components. Wash racks are available (illustration below).

Protecting the cage from the room and the room from the cage is the Maxi-Miser Mobile Change Station. The Maxi-Miser Mobile Change Station creates an air curtain of high velocity air and a work area of low velocity, class 100 air that minimizes the interaction of air from the cage to the room and the room to the cage. A large work surface makes cage changes easy. The unit is available with an optional, easy to reach feed hopper.

Maxi-Miser Features:

• Inhibits the transmission of airborne diseases between cages
• Enables different species to be housed in the same room
• Minimizes energy required to maintain ideal cage environment
• Allows more animal housing per square foot of floor space
• Superior air exchange reduces infant diarrhea and animal mortality
• Improves the working environment for allergy sensitive staff members
