MSP® DEHUMIDIFICATION
Welcome to MSP® Technology, a world leader in GREEN dehumidification and energy recovery solutions. MSP products save energy, save precious water, and provide the best possible indoor air quality. MSP Technology offers dehumidification and energy recovery components for specification in, and adaptation to, air handling equipment.
Multiple Small Plate (MSP®) technology saves energy. It achieves superior heat transfer capacity, with low air pressure drop. The advantage is in MSP Technology’s patented design that provides every benefit that could possibly be offered to engineers and owners—and yet the design is economical. The difference is in the MSP Heat Exchanger, not exotic materials or expensive machinery. MSP Technology’s heat exchangers are designed to provide every benefit that you could possibly offer building engineers and owners.
MSP Technology offers a wide range of solutions which incorporate our patented multiple small plate design in “wrap‐around plate,” unitary dehumidifying coil products. For all types of energy recovery applications, from industrial process to commercial buildings to one‐of‐a‐kind units to large commercial systems, MSP's Technology can be tailored to any need.
MSP products offer greater efficiency, dramatically reduced energy consumption and superior indoor air quality that can earn your project LEED® GREEN building points.
LEED, or Leadership in Energy and Environmental Design, is an internationally‐recognized green building certification system. Developed by the U.S. Green Building Council (USGBC) in March 2000, LEED provides building owners and operators with a framework for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions.
LEED promotes sustainable building and development practices through a suite of rating systems that recognize projects that implement strategies for better environmental and health performance. The LEED rating systems are developed through an open, consensus‐based process led by LEED committees, diverse groups of volunteers representing a cross‐section of the building and construction industry. Key elements of the process include a balanced and transparent committee structure, technical advisory groups that ensure scientific consistency and rigor, opportunities for stakeholder comment and review, member ballot of new rating systems, and fair and open appeals.
The United States Green Building Council defines a green product as fulfilling one or more of the following five categories: Indoor environmental quality, Energy efficiency, Water savings, Materials selection and Sustainable site development. The MSP Unitary Dehumidifying Coil is eligible for USGBC LEED®* credits and fits easily into at least three of these five categories:
Indoor air quality (IAQ): The MSP® Dehumidifying Coil provides ventilation with controlled humidity, giving building occupants a comfortable and healthy environment.
Energy efficiency: The MSP® Dehumidifying Coil consumes significantly less energy than competitive dehumidification products.
Water savings: Water runoff from condensation is significant and can be used for grey‐water applications such as irrigation and flush water. With proper filtration, this water is also suitable for drinking. It is estimated that a 10,000‐CFM MSP Unitary Dehumidifying Coil, operating in a 24/7 application (such as a hospital or hotel) in Miami Florida, will output almost 1‐million gallons of water annually.

PRINCIPLEOFOPERATIONThe MSP unit is designed to dehumidify air using the wrap‐around plate technology. Air is cooled, dehumidified and reheated in a three‐step process:
1. Warm, humid incoming air (T1) flows through the first pass of the plate type air‐to‐air heat exchangers for pre‐cooling and initial dehumidification (T2). This is accomplished by regenerative thermal exchange with the cooler air (T3) that is leaving the heat exchanger (see step 3). Pre‐cooling and dehumidification by regenerative thermal exchange are "free" and involve no additional equipment.
2. Pre‐cooled air (T2) then passes twice over conventional cooling coils for final cooling and dehumidification (T3) Pre‐cooled and pre‐dehumidified air can be treated much more efficiently, using smaller compressors that require as little as one‐half the power of conventional dehumidification technologies.
3. The cool, dehumidified air (T3) is then drawn back through the opposite side of the heat exchanger where it absorbs some heat from incoming air (see step 1) and continues on to the building's HVAC system (T4). No heating coil (and associated energy penalty) is required to reheat the dehumidified air before it enters the conditioned environment.

PRODUCTOVERVIEWBYATHIRDPARTYLEED®ACCREDITEDPROFESSIONALGREEN FEATURES OF THE MSP TECHNOLOGY DEHUMIDIFICATION SYSTEMS
The MSP Technology’s dehumidification system is a high efficiency and intelligent product. This system is
extremely cost effective, particularly in humid climate zones and where hours of operation are long (such as in
hotels, public housing, laboratories, factories, cleans rooms and hospitals). This system uses an internal air‐to‐
air heat exchanger to regulate the temperature of dehumidified air; this minimizes the amount of energy
needed to operate the system and thus greatly reduces energy costs. Since this system has an internal heat
exchanger, it can be driven with chilled water. This feature is especially useful in cities, metropolitan areas and
campuses where central chiller plants are common.
The Electronically Commutated (EC) fan motors used to run this high efficiency system are on the cutting‐edge.
These motors are a quantum leap in fan performance because high efficiency is maintained throughout the
range of fan speeds. EC motors have “built‐in” speed control. Heat producing VFD’s are not necessary – and this
translates into more energy savings.
On top of these benefits, it is well known in the green building industry that humidity can cause major problems.
In humid climates, moisture can build up on the surfaces of rooms, and even penetrate to the interior walls. This
may cause mold problems and lead to health problems for building occupants and maintenance issues over
time. Given this, the MSP Technology’s dehumidification system is a long‐term, practical, sustainable choice; not
only will you be reducing energy costs but you will also be protecting your building materials and protecting your
building occupants.
The triple bottom line is that the MSP Technology dehumidification systems excel in providing:
Extraordinary energy savings (as much as 50% more efficient than other systems);
Occupant comfort (removing humidity is the key to a comfortable thermal environment) and;
Building maintenance savings over time (less moisture means less mold and less maintenance).
When you pair this triple bottom line with the environmental benefits of this product LEED wise, what you have is
a superior dehumidification system. It’s a win‐win on many levels. Don’t pass this one up!

To Whom It May Concern:
This letter is to verify that the MSP Technology’s dehumidification systems can help project teams achieve
LEED® Certification. The nature of these systems makes them of a high environmental quality.
MSP dehumidification systems always help projects qualify for LEED Energy and Atmosphere Credit 1,
Optimize Energy Performance. This technology could earn from 1 to 10 points by making buildings up to
50% more efficient than if they were to use standard units. MSP Technology has software that may be
used to explicitly prove energy performance values.
The thermal comfort resulting from using MSP Technology systems contributes toward LEED Indoor
Environmental Quality Credits 7.1 and 7.2, Thermal Comfort Design and Verification.
MSP dehumidification systems may be used to qualify for LEED Water Efficiency Credits 1.1 and 1.2,

NOTES: 1) Factors such as coil circuiting and loading can restrict choices to specific models within a CFM range. Where possible, select models where the last two
digits are an even number (IE; 0708, 0304). Selections must be confirmed with factory before ordering. 2) Recommended maximum SCFM. We recommend selecting a model equal to, or greater than, the desired SCFM plus 10%. 3) Dimension “W” varies with header diameter. Selections are based upon maximum header diameter. 4) Overall height is governed by coil rows and manifold angle. Tables are based on the manifold angle shown, and can be adjusted if required. 5) Weights can vary due to materials of construction. Weights herein are based on 16 gauge galvanized steel construction
MSP’s policy of continuous product improvement, requires that dimensions and weights can change without prior notice

NOTES: 1) Factors such as coil circuiting and loading can restrict choices to specific models within a CFM range. Where possible, select models where the last two digits are an even number (IE; 0708, 0304). Selections must be confirmed with factory before ordering.
2) Recommended maximum SCFM. We recommend selecting a model equal to, or greater than, the desired SCFM plus 10%. 3) Dimension “W” varies with header diameter. Selections are based upon maximum header diameter. 4) Overall height is governed by coil rows and manifold angle. Tables are based on the manifold angle shown, and can be adjusted if required. 5) Weights can vary due to materials of construction. Weights herein are based on 16 gauge galvanized steel construction
