The “D” Energy Box

The "D" Energy Box is a complete renewable energy system with the capacity to displace more than 5,500 gallons of #2 fuel oil delivered to site in a mobile container constructed of 2-3/4” cross laminated wood panels. The cross laminated timber panels are made from laminas of black spruce glued the entire length of the surface and screwed at the junctions with frame rails; the result is an environmentally friendly, weather tight, rugged, 1-hour fire rated, attractive container with the ability to produce 382,000 BTU/Hr. All penetrations from the storage room to the boiler room and from the boiler room outside are designed fire resistant, fire inhibiting or flame-propagation-proof.

The floor and the ceiling of the Energy Box Boiler Room are covered with aluminum diamond plate. The roof is completely wrapped with ice and water shield and finished with steel roofing with the capacity to handle 70lbs/ft2 snow load. The exterior is trimmed with 5/4” pine and entirely covered with two coats of wood preservative and is expected to be sided to match surrounding buildings within two years of delivery. The bottom beams are Smart Sense pressure treated lumber.

Technical equipment of the Energy Box

Electrical equipment
The Energy Box is electrically preinstalled:
 
  • In the entrance area is a service power socket 120V.
  • Fluorescent lighting is installed on the ceiling of the container.
  • An emergency shut-off switch is located inside the Energy Box near the entrance door. The emergency shut-off cuts the power supply to the boilers. The interior lighting continues to work for security reasons.
  • Each Boiler has its own 220v 20amp circuit breaker
Note: Pelletronic Online is available at additional cost.
 
Hydraulic Equipment
Each boiler in the Energy Box is hydraulically preinstalled without circulator pumps (the contractor is responsible for sizing, supplying and installing the circulators.) Flow and return of each boiler are connected to two 3” headers. The headers must be connected on site to the long distance flow and return pipelines.
 
Each boiler has its own safety valve. Each Box has an appropriately dimensioned expansion vessel.
 

Site preparations for installing the Energy Box

To be provided on site by contractor or third party:

  • Location of the Energy Box site
  • Necessary Permitting
  • Foundation of the Energy Box
  • Rain water drainage
  • Electrical connection of the Energy Box
  • Hydraulic connection of the Energy Box
Planning of the Energy Box Type D
Note: In planning for the installation of the Energy Box please follow all local, state, and federal building codes and emissions requirements (the MESys Energy Box carries an outdoor boiler hangtag for Maine and Vermont and is ASME approved. No hangtag is required in New Hampshire.)
 
Foundation of the Energy Box Type D
The Energy Box can sit on a double strip T style foundation or a foundation slab. Both foundations types must be protected against frost and placed on properly compacted substrate. Proper foundation drainage and water shed grading should be taken into consideration during preparation.
 
The foundation MUST be frost-resistant.
You must communicate with MESys to locate the position of the utilities for proper connection. Close the utility penetrations after the connections are made and protect them against frost, dirt and vermin. In the connection location you need the following connections and conduits:
 
  1. Flow heating system
  2. Return heating system
  3. Electrical connection 220v/110v, 60amp minimum as per N.E.C.
  4. Communications cable (optional for Internet Monitoring)
  5. Foundation grounding
  6. Empty conduit for future use (recommended)
Electrical connection of the Energy Box
The electrical installation has to be made by an authorized professional, and must meet N.E.C. and local requirements.
