Modular Design

Heats in Packs: Modular Zero Side Clearance Design

Velo is built for mechanical rooms where floor space is the constraint. Its modular form factor supports side-by-side placement with zero side clearance, so you can fit more capacity into the footprint you already have.

Supports tight layouts where tanks, piping, and access compete for space
Helps reduce the “Tetris effect” during retrofit planning
Minimal service clearances with easy servicability

Fits in Tight SPaces

Goes Anywhere: Fits Through Doors, Freight Elevators

Velo is built for the projects that stall at the loading dock. It fits through a standard 36" doorway, rides a freight elevator, and ships ready to set with no assembly required. That means fewer access surprises and fewer jobsite workarounds.

Retrofits with limited access paths
Mechanical rooms with narrow corridors or standard doorways
Sites where a crane is not practical

Return-to-Primary Single-Pass

Omni-Pass: Return-to-Primary for More Efficiency

Velo supports single-pass, multi-pass, and return-to-primary piping strategies. Nyle calls this Omni-Pass™. With return-to-primary capability, many designs can avoid swing tanks, reduce tank count, and simplify the overall system.

Single-pass capability with no swing tanks required
Fewer tanks and cleaner piping in many layouts
Up to 50% more system efficiency with single-pass return-to-primary

Additional Features

Trusted Engineering, Primal Power

More power per square inch

For its size, Velo “packs a punch.” It uses variable speed technology to hold capacity at low ambient within a smaller footprint. Nominal DOE capacity at 180,000 BTUs.

Cold-climate e-Series platform

Velo is part of Nyle’s e-Series cold-climate heat pump family. It is designed for a wide range of weather conditions, indoors or outdoors. Velo has a 1000-hour salt spray rating.

15 horsepower class

Velo is exempt from the operator requirements to install and maintain large commercial heat pumps in New York City. Cheaper to install and maintain compared to other products in its class.

Quiet operation

Mechanical rooms are loud enough. Velo targets quieter operation while keeping Nyle’s ductability. With a max sound pressure of 74.6 dBA and 4.54 in. of external static pressure.

High-efficiency Nyle water heating systems with air source heat pumps and advanced configurations.

Frequently Asked Questions

One unit can support these DHW configurations: (1) single-pass with a swing tank, (2) single-pass return-to-primary (no swing tank), and (3) multi-pass. The unit must be set up to match the piping configuration used.

Return-to-primary means the building recirculation loop returns to the primary storage tank rather than a swing tank. This can reduce system complexity compared to a swing-tank approach. Follow the manual’s piping details for valves, strainers, and sensor placement.

Yes. Velo is fully ductable on both intake and discharge. Duct design must account for service access and allowable static pressure.

Not always. Velo can run in return-to-primary configurations that do not use a swing tank. Some designs still use a swing tank, depending on project goals and layout.

For ductless intake, Velo can be installed directly side-by-side with no side clearance requirement. Optional side clearance can make some maintenance tasks easier.

Yes. Velo includes an integral circulator. The submittal lists design flows, pressure drops, and external head allowance by mode.

Common options include a BMS Gateway, a main control panel for staging multiple units, and a remote outdoor sensor for interior ducted applications.

Yes, outdoor installation is supported. Cold-climate installs require proper piping protection, freeze protection planning, and power planning per the installation manual.

Velo can support recirculation in multiple system configurations, including return-to-primary setups. Use the manual’s piping guidance for recirc pump placement and minimum flow expectations.

The ambient operating range is 10°F to 120°F.

Maximum service water temperature is 160°F.

Nominal DOE capacity is 180,000 BTU/hr. AHRI 1160 capacity is 157,000 BTU/hr at the listed AHRI test conditions.

Nominal DOE performance is 4.1 COP. AHRI 1160 performance is 3.2 COP at the listed AHRI test conditions.

Performance varies by ambient temperature. The submittal includes capacity and COP data down to 10°F for both heat-recovery (single-pass demand) and multi-pass demand modes.

Velo uses R513A refrigerant. (Why not CO2? Learn the little-known truth here.)

Velo is available in 208–230V 3-phase 60Hz or 460V 3-phase 60Hz. Electrical values (MCA/MOCP) vary by power package. Control power is 120V single-phase 60Hz.

The standard power approach supports freeze protection power needs and service design. The Unified Power Package option consolidates feeds into a single-point power configuration. Use the submittal option list when specifying.

Domestic water connections are 1-1/2 in FPT. Condensate connection is 1 in.

Refer to the submittal and manual for exact dimensions and rigging notes. The installation manual lists dry and operating weights and calls out top lift points for rigging.

The easiest way to size a system is request a selction from the Nyle applications team. Responses are quick and thorourgh.
