Stainless, vertical, firetube, commercial, condensing

Serviceability features: The SVF line features a stainless steel vertical fire tube and shell heat exchanger design for best-in-class corrosion resistance, along with intuitive, user-friendly control systems to make installation and operation easy. The color touchscreen Unity 2 and NURO controls are included as a standard feature, enabling advanced diagnostic and troubleshooting, along with remote monitoring capability. Furthermore, the line features industry-leading thermal efficiency up to 98%, unrivaled ease of maintenance, and Weil-McLain boiler design reliability and longevity.

Noise-reduction features: A smartly designed sealed cabinet provides whisper-quiet operation. An insulated heat exchanger and domestic hot water pipes reduce heat loss and noise while a sound suppressing air silencer on the heat exchanger suppresses potential nuisance tones.

IAQ equipment supported: Manufacturer did not specify.

Thermostat compatibility: Compatible with most thermostats.

Replacement parts compatibility: Shares replacement parts with other models.

Additional features: The Unity 2 controller simplifies boiler system design for specifying engineers and improves control interface commonality and communication across the entire product line. Similarly, the 7-inch NURO touchscreen control system monitors and modulates combustion and ignition levels to maintain desired outlet temperatures, allowing users to maximize efficiency. Real-time visual alarms with diagnostics and troubleshooting tips, variable-speed pumping, and connected remote monitoring grant the ability to control a boiler system anytime, from anywhere.

Warranty information: All units are tested and certified to the industry’s highest standards and include a warranty of up to 10 years on the heat exchanger and up to two years on parts with registration.

Special installation requirements: SVF boilers are designed with the contractor in mind and include setup and installation features that save time, labor, and money. The boilers are shipped in a fast-removal crate with an integral unloading ramp. Industrial-grade roller casters allow for placement in tight spaces and without fork truck requirement. Additionally, a door-fit design allows for passage through standard 36-inch doorways, while an integrated burner-in-cover plate design minimizes overhead design requirements to just 18 inches.

Water-to-water, compound centrifugal

Serviceability features: The CYK-400 streamlines serviceability. Centrifugal compressors are open-drive type, and thus the compressor and motor are separate allowing for easier serviceability.

Noise-reduction features: Patented OptiSound control minimizes operational sounds and vibration levels. This feature continuously monitors the characteristics of the compressor-discharge gas and optimizes the diffuser spacing to minimize gas-flow disruptions from the impeller. This innovative technology improves operating sound levels of the unit an average of 7 dBA and up to 13 dBA on the largest models. It can also reduce part-load sound levels below the full-load level.

IAQ equipment supported: Manufacturer did not specify.

Thermostat compatibility: Not used with thermostats but compatible with most building automation control systems.

Replacement parts compatibility: Some shared parts and some unique parts.

Additional features: The York CYK-400 heat pump is engineered to drive decarbonization within existing commercial buildings. Using two electric, motor-driven, centrifugal compressors arranged in series, the heat pump delivers high-temperature hot water up to 170ºF and can achieve simultaneous hot and chilled water cooling all within a compact design. Combined with an innovative double-bundle condenser and variable-speed drives, the CYK-400 can manage unbalanced load conditions and is three to five times more efficient than a traditional boiler and chiller combination.

Warranty information: Standard and optional extended product parts and labor warranties.

Special installation requirements: The CYK-400 delivers high-temperature hot water up to 170ºF, making it compatible with most HVAC infrastructure within existing commercial buildings and eliminating the need to replace air handlers and terminal heating devices. Additionally, its compact, flexible design provides advantageous space-saving benefits to further streamline installation.

Serviceability features: These RTUs feature a best-in-class user interface, adjustable height display, startup wizard, and user-adaptable parameters to help expedite commissioning. The Ducted Systems Solutions app allows contractors to simply scan a unique QR code on each RTU, which enables on-demand access to unit-specific details, technical literature, and direct connection to technical support. Optional features include service viewports, internal lights, separate high- and low-voltage doors, magnehelic filter gauges, and adjustable height singe-point latching doors.

Noise-reduction features: Sound attenuator and compressor sound blanket options minimize sound outputs.

IAQ equipment supported: Ultraviolet lights, humidifiers, final filters, and modulating hot gas reheat.

Thermostat compatibility: Manufacturer did not specify.

Replacement parts compatibility: Does not share replacement parts with other models.

Additional features: The 25- to 150-ton Premier RTUs provide up to 31% greater efficiency at part-load than is required, depending on the standard. They exceed the Department of Energy 2023 energy efficiency standards, and most tonnages meet the stringent Consortium for Energy Efficiency 2024 highest tier ratings. They combine variable-speed compressor options, variable-speed drive fan options, and low-GWP R-454B refrigerant with advanced airflow and heat transfer technologies to deliver a highly optimized system.

Warranty information: Standard one-year parts and either a 6-month or one-year promotional labor warranty when started by a certified contractor. Extended warranties can be purchased up to five-year parts and labor, including the compressors.
