Our systems support multiple heating methods: electric heaters (staged or SCR-modulating), hot-water coils (2- or 4-pipe), and DX heat pump configurations where applicable. Selection depends on building energy source, capacity, and control strategy. We can integrate with boilers or district hot water via control valves and sensors.

Heating capacity is based on heat loss calculations (envelope, infiltration, ventilation). For preliminary estimates, use design temperature difference for your location, building U-values, and air change rates. Final selections should be validated with a Manual J/S (residential) or ASHRAE-based load calc (commercial/data centre) and safety factors per spec.

In zoned systems yes—via separate circuits or dedicated units. In single-zone CRAC/CRAH units, the controller provides either/or logic to maintain supply/room setpoints, with deadbands and lockouts to avoid hot–cold short cycling.

Yes. Options include energy recovery ventilators (ERV/HRV), refrigerant heat reclaim for reheat, and waterside heat recovery using fluid coolers or economizers. Controls coordinate recovery with demand and outdoor conditions.

We supply direct expansion (air- or water-cooled), chilled-water units (with 2- or 3-way valves), and integrated economizer options (airside or waterside) depending on climate and data centre design. Redundancy (N+1) and dual-cool systems are available for mission-critical applications.

Use downflow for raised-floor distribution to cold aisles; select upflow for overhead ducted supply. Selection depends on room layout, cable trays, and containment strategy. Our engineers can review drawings to advise the optimal discharge configuration.

Typical supply/room temperature targets are 22–27°C with relative humidity 20–60% (dew point control preferred). Exact ranges follow project specifications and standards; tighter bands may be used for sensitive equipment.

Yes. Units can be configured for containment with pressure control, variable fan speed, and temperature sensors placed at server inlets to maintain SLA setpoints and reduce mixing losses.

Standard protocols include Modbus RTU/TCP, BACnet MS/TP or BACnet/IP. SNMP monitoring is available for IT environments. Points lists (read/write) are provided for seamless BMS integration.

Yes. Controllers can rotate lead/lag, share load (teamwork), and stage compressors, valves, heaters, and fans to maintain setpoints efficiently. Rotation reduces runtime imbalance and extends equipment life.

Remote monitoring via web UI or BMS is supported. Alarms (high temp, humidity out-of-range, filter dirty, leak detection, power issues) can be logged and sent via network protocols for quick response.

Typical sensors: supply/return air temp & RH, coil sensors, differential pressure (filters/room), condensate, and leak detection. In data centres, place temp sensors at server inlets; in offices, use representative zone returns away from heat sources.

Standard voltages include 208–230V and 460–480V, 3‑phase, 50/60 Hz depending on region. Nameplate MCA/MOP are provided on submittals. Options include dual power feeds, ATS compatibility, and UPS-friendly control power.

EC fans or VFD-driven blowers are standard for airflow modulation. Compressors may use inverter drives or soft starters based on model. This reduces inrush, improves efficiency, and enables tighter control.

Units include integrated disconnects where specified. Maintain code-required working clearances at the electrical side. Follow local electrical codes for conductor sizing, grounding, and OCPD per MCA/MOP.

Yes. We recommend SPD on main feeds and sensitive control circuits, especially in mission-critical installations.

Confirm access paths, pad/curb readiness, condensate routing, power availability, communication cabling, and crane/rigging plans. Review submittals for dimensions, weight, connection sizes, and lifting points.

Provide trapped drains with proper fall and a maintenance cleanout. For negative pressure plenums, use deep traps or pumps. Insulate cold lines to avoid sweating; include leak detection as needed.

Yes. Startup/commissioning checklists are available. We can arrange factory or field commissioning, including sensor calibration, control setpoint tuning, alarm verification, and performance documentation.

Follow manufacturer guidelines for line length, trap placement, oil return, nitrogen purge during brazing, and dehydration. Pressure test and evacuate to industry standards before release.

Typical program: monthly visual checks; quarterly filter changes and coil inspection; semiannual electrical tightening and drain cleaning; annual sensor calibration, belt inspection (if applicable), and controls review. Data centres often adopt more frequent intervals due to uptime requirements.

Using differential pressure sensors or gauge: when ΔP exceeds the set threshold or runtime limit. Many controllers generate a “dirty filter” alarm based on DP or estimated runtime.

In redundant (N+1) systems, maintenance can be staggered with load sharing. Use isolation valves and bypasses on hydronic circuits; coordinate controls to keep room within setpoints during service.

Recommended spares: filters, belts (if belt-driven), fuses, contactors, relays, sensors, actuators/valves, EC fan modules, and controller HMI. For critical sites, keep a compressor kit or fan assembly per fleet size.

Standard equipment warranty typically covers 12–18 months from shipment or 12 months from startup (whichever occurs first), with optional extended coverage. Exact terms will be per your sales agreement.

Contact CANATAL support with model/serial numbers, fault description, and site photos/logs. We’ll assist with troubleshooting, parts identification, and next steps. A service plan is available for proactive care.

Yes. With networked controllers, we can review alarms, trends, and setpoints remotely (subject to site security policies) to accelerate root-cause analysis.
