Commercial Power with High Efficiency Inverter Technology The Fairland InverX Jumbo range brings high performance full-inverter heating to large commercial pools, leisure centres, school facilities, and luxury estates. Powered by TurboSilence full-inverter technology, the InverX Jumbo achieves an extraordinary COP of up to 17, delivering up to 17 times energy savings compared to traditional commercial direct electric or on-off heating systems.

Sub-Zero Performance Down to -20°C Engineered for severe ambient environments, the InverX Jumbo operates seamlessly in outdoor air temperatures as low as minus 20 degrees Celsius. By capturing environmental heat even in sub-zero conditions, it ensures reliable year-round climate management for high-demand aquatic facilities.

Three Intelligent Commercial Operating Modes Tailor heating output effortlessly to operational demands:

Turbo Mode: Delivers a 120 percent heating boost for fast initial startup or rapid thermal recovery.
Smart Mode: Automatically adjusts output between 20 percent and 100 percent capacity to maintain steady water temperature with optimal energy efficiency.
Silence Mode: Operates at 20 percent to 60 percent capacity for whisper-quiet performance during off-peak hours or evening swimming.

Quiet Operation and Soft-Start Protection Despite massive thermal output, the InverX Jumbo operates up to 15 times quieter than standard commercial pool heaters, with sound pressure at 10 metres dropping as low as 22.1 decibels. Built-in soft-start electrical protection eliminates high inrush currents upon startup, safeguarding commercial electrical switchgear and main circuit breakers.

Tiered Long-Term Commercial Warranty Package

7-Year Overall Unit Warranty: Comprehensive coverage across all mechanical components, fan motors, and control electronics.
15-Year Compressor Warranty: Extended long-term guarantee for the high-efficiency commercial inverter compressor.
15-Year Heat Exchanger Warranty: Complete protection against corrosion from pool chemicals and salt water systems.

Installation & Operating Guidelines

Electrical Infrastructure Verification: Ensure your plant room supply provides 400V Three Phase power with a dedicated 25A breaker for the JBR150T or a 48A breaker for the JBR300T.
Footprint & Clearance: Position the unit outdoors on a reinforced concrete pad rated for heavy commercial equipment (217 kg for JBR150T, 476 kg for JBR300T), maintaining adequate clearance around air intake and exhaust.
Commercial Plumbing: Connect 75mm (JBR150T) or 90mm (JBR300T) pipework into the heat pump unions downstream of primary filtration.
Control & Monitoring: Configure the digital interface for automatic defrost routines and pair with the optional smartphone app for remote monitoring.

Frequently Asked Questions

What size commercial pool does the InverX Jumbo heat pump range suit? The JBR150T is ideal for commercial pools from 130 to 260 cubic metres, while the JBR300T supports large pools from 260 to 520 cubic metres, assuming a covered pool running at least 15 hours daily.

Can the InverX Jumbo operate in freezing winter conditions? Yes. The unit operates efficiently in ambient air temperatures down to minus 20 degrees Celsius with automatic defrost functionality to prevent ice buildup.

What electrical supply is required for the InverX Jumbo? Both models require a 400V Three Phase electrical supply. The JBR150T requires a 25A circuit breaker, whereas the JBR300T requires a 48A circuit breaker.

What warranty protection is included with commercial Jumbo models? Every Fairland InverX Jumbo heat pump includes a 7-year overall manufacturer warranty, paired with 15 years coverage on the inverter compressor and 15 years coverage on the titanium heat exchanger.
