Ecology Unit – HEL-12000

The Ecology Unit HEL-12000 is the highest-capacity model in the HEL range, purpose-built for large-scale food service operations where exhaust volume, grease load, and regulatory compliance demands exceed what smaller units can handle. With three parallel electrostatic cells delivering a combined 21.6 m² of total collecting area, the HEL-12000 processes up to 12,000 CMH of contaminated kitchen exhaust — three times the capacity of the HEL-4000  while maintaining the same certified MERV 15 filtration rating and 99% double-pass efficiency.

Built into a reinforced galvanized steel enclosure measuring 650 × 1,840 × 595 mm and weighing 124 kg, this unit is designed for permanent installation in mechanical rooms serving hotel ballrooms, hospital central kitchens, large restaurant chains, and industrial catering facilities. The three-cell architecture not only multiplies collection capacity  it also provides redundancy, allowing one cell to be removed for cleaning while the remaining two continue to operate, minimising downtime in mission-critical kitchens that cannot afford ventilation interruptions.

Ideal Applications – Who It’s For

5-Star Hotels & Resort Kitchens

Multiple simultaneous dining outlets — all-day dining, banquets, room service  can feed into a single HEL-12000 with capacity to spare, simplifying the mechanical room layout.

Hospital & University Central Kitchens

At 12,000 CMH with BMS integration, the HEL-12000 meets the strict ventilation compliance requirements of healthcare and education facilities operating under Saudi MOH and MOMRA codes.

Flagship Restaurants (300+ seats)

High-volume à la carte kitchens with 6–10 active cooking stations need airflow exceeding 8,000 CMH at peak service. The HEL-12000 handles this with a 33% headroom buffer.

Central Catering & Food Production Facilities

Industrial-scale cook-chill and cook-freeze operations with continuous high-temperature cooking demand the sustained grease capture that only a 3-cell architecture can provide.

Convention Centres & Stadium Kitchens

Event-based kitchens that switch between low-load standby and extreme peak demand benefit from the HEL-12000’s auto-intensity control, which adjusts electrical output to match real-time load.

Multi-Restaurant Developments

A single HEL-12000 can serve a shared exhaust riser serving multiple food & beverage outlets in a mixed-use tower, reducing capital expenditure versus installing individual units per tenant.

Frequently Asked Questions – HEL-12000

What is the estimated monthly electricity cost for the HEL-12000?

Running at 300 W (without UV) for 16 hours a day, 26 days per month, the unit consumes approximately 124.8 kWh/month. At the Saudi Electricity Company commercial rate of SAR 0.18/kWh, that is roughly SAR 22.46 per month — a cost-per-CMH-treated that remains highly competitive at this capacity class. With the UV system enabled at 900 W, consumption rises to approximately SAR 67/month.

Can two HEL-12000 units be connected in parallel for kitchens larger than 12,000 CMH?

Yes. The HEL-12000 is designed with “Multiple Units Stack” capability as a standard installation mode. Two units operating in parallel deliver up to 24,000 CMH from a combined footprint of 650 × 3,680 mm. Both units connect to the same BMS terminal block, allowing unified monitoring and control from a single building management interface.

How is the 3-cell cleaning schedule managed in a 24/7 kitchen?

The three electrostatic cells can be maintained on a staggered rotation. For a kitchen operating 18+ hours daily, a practical schedule is to clean one cell every two weeks — meaning each cell gets a full clean every six weeks. With a cell removed, the two remaining cells still process approximately 8,000 CMH, maintaining ventilation compliance during the 45–60 minute cleaning window.

What structural requirements must be met before installing the HEL-12000?

The unit weighs 124 kg and measures 650 × 1,840 × 595 mm. The mounting structure — ceiling hangers, support frames, or equipment rails — must be rated for a minimum static load of 200 kg to include the weight of accumulated grease and service personnel access. A clear installation corridor of at least 2,000 mm width is required to manoeuvre the unit into position. We recommend involving a licensed MEP contractor for structural sign-off prior to installation.

Does the HEL-12000 comply with Saudi building and environmental codes for large food service facilities?

The HEL-12000’s MERV 15 rating and up to 99% grease capture efficiency (double-pass, ASHRAE 52.2-2012) satisfy the air quality and emissions standards mandated by Saudi Arabia’s General Authority for Meteorology and Environmental Protection (PME) for commercial food service exhaust. The BMS terminals also support documentation and reporting requirements for ISO 14001-aligned environmental management systems.
