Products>Custom HVAC>Large Air Handlers We have built some of the largest air handling units in the world for clients who demand highly engineered solutions. We are experts in designing and building large air handlers that have to fit in tight spaces piece by piece, for simple field assembly. We employ computer numerically controlled (CNC) production technology that reduces human error and allows for precise and accurate manufacturing of components. Some of the featured technology includes: Integral to all of our products our frames incorporate: Floor designs optimized to eliminate “oil canning” deflections and “welding warp” Intermediate channel members aligned with fan isolation housings Heavy gauge checker plate flooring welded to perimeter and intermediate channel Frame is arched during fabrication Insulated using either urethane foam or fiberglass insulation clad with galvanized steel Cabinets, Casing and Doors Our cabinets are designed as per SMACNA (Sheet Metal and Air Conditioning Contractors’ National Association) standards:

“Plenum-Lock” casing panels, recommended construction method according to SMACNA 12,14,16, or 18-gauge galvanized, satin-coat steel, aluminum or stainless steel Casing Panels engineered to accommodate: Pressure gradients generated during operation 2” to 6” thickness of insulation Static and dynamic loading of final structure Mating Surfaces of casing panels pre-silicon sealed Casing panels screwed together along their length at 4-inch intervals Casing panels are designed with a 1 ¼ inch lip Panels riveted to the base frame via the z-bar that is welded to the structural plate Panels sealed with polyurethane compound to ensure an impenetrable, water proof barrier Panels externally fastened with rivets Mitered corner frames tig welded together, view ports with automotive style bulb seal Door frames with filleted corners for a better seal Doors are tig welded in the corners for added rigidity Our units can incorporate: Plenum Fans-Airfoil, DWDI Airfoil, multiple fan arrangements using direct drive plenum fans, forward curve, 1” or 2” spring isolation, standard open spring (housed and seismic), equipment guards are standard.

To ensure the structural and aesthetic integrity of our units, we apply the following:my ac unit not cooling Automotive-grade sealant is applied to all exterior seams of assembled unitmobile home hvac repair Two-component acrylic-urethane paint is applied to the unit after sealant applicationauto shops in tampa Colored in compliance with customer’s request Our units can incorporate the following controls and electrical features PLC based control systems (CAREL technology), local and remote control implementation Standard Alphanumeric or HMI terminals, BMS integration (BacNET/IP/Ethernet) N+1 redundant control strategy Communication flexibility with various BMS supervisory systems FieldBus ports available for industrial devices control

Increased security system functionality and reliability by customized control techniques CEC/NEC/IEC Electrical Code Standards In line with our commitment to quality, Silent-Aire custom HVAC units also feature: Coils secured with hat tracks allowing coils to be slid into or out of units easily, via side access doors. Filter banks, coils and all other internal partitions are sealed to the internal side of the exterior wall and roof panels to ensure zero air by-pass. Sloped stainless steel drain pans recessed within structural floor. Roof curbs are manufactured from 10 to 12 gauge galvanized steel. Quality Control and Industry Certifications Our commitment to quality is exemplified through our in-house quality assurance program. Every unit that leaves our factory is carefully inspected and tested to ensure that our clients receive only the best. Our design, engineering and production teams work in accordance with the standards of the various governing bodies within our industry and our products have been awarded with recognized industry certifications.

The problem: the mechanical room was in the center of an office filled with employees on the sixth and seventh floors. With the need to upgrade the system, but without disrupting business, this commercial business chose F.E. Moran Mechanical Services as the lead contractor to coordinate the difficult task.Numerous Hurdles Conquered over Holiday WeekendDue to the location of the mechanical rooms, this project was certain to have obstacles. The first, F.E. Moran had to install a new air handling unit in the center of two occupied floors without disrupting business or disturbing the facility.

To solve this problem, the installation was scheduled over the Thanksgiving holiday, to avoid disturbing employees. However, this tight timeline posed its own difficulties. The F.E. Moran Mechanical Services crew now had to tightly coordinate the installation and all sub-contractors scheduled work to ensure all work was complete before employees arrived Monday morning. The dismantling of the old air handling system posed a new problem. The old air handling unit was built in 1982. It was so large it needed to be dismantled piece by piece to remove it, and the mechanical room needed to be re-structured. The original air handling unit was obtrusive, providing only a foot of space for service personnel to work. Additionally, a vestibule was inside the already small mechanical room, and needed to be taken down without disturbing employees or blemishing the building.The final hurtle was moving the new air handling unit onto the sixth and seventh floors without disturbing the building. With the issue of moving a large air handling unit and an additional problem of only having passenger elevators to move it in, the team needed to think outside of the box.

Creative Thinking Provides Solid SolutionsF.E. Moran Mechanical Services was hired as the lead contractor, putting them in charge of coordinating all sub-contractors. Mr. Maloni made a color-coordinated schedule for all contractors, detailing when and where each contractor needed to be. Mr. Maloni worked around the clock the days before the project began to ensure perfect coordination and set-up, ultimately resulting in only two hours of sleep between Tuesday and Thursday. Contractors worked from Tuesday morning to Sunday evening, working straight through Thanksgiving. The crews celebrated Thanksgiving together with turkey chili delivered the morning of Thanksgiving by Mr. Maloni's wife.To move the air handling unit into the building, three foremen, Mike Jones and Chris Waprairski of Mechanical Services and Mike Strezo of F.E. Moran, built a custom dolly that angled the pieces of the air handling unit into an arrangement that fit into the passenger elevator without scuffing walls, floors, or ceilings.

The team built mock up equipment to test paths and angles to ensure the interior remained flawless. In the F.E. Moran shop, the air handling unit was dismantled for passage. The custom dolly seamlessly transported the unit without issue.Now, the team had to rebuild the air handling unit in the tight mechanical room. To do this, the team added temporary structural beams above the actual structural beams and used them to hoist the 3,000 pound equipment using chain falls into the air to piece the air handling unit together like a puzzle. Mr. Maloni described it as, "building a ship in a bottle."Mission Accomplished in Six DaysF.E. Moran completed the project in six days. By Monday morning, employees entered their offices without incident. The sixth and seventh floors were clean and back in working order.Now the commercial facility had a new, energy efficient air handling system with a smooth, non-disruptive installation. The new air handling unit had many benefits. It was much smaller than the original, providing usable room in the mechanical room for service.
