Product overview

Heavy-duty silent diesel generator sets for sites without a reliable grid

70 kW prime / 77 kW standby — 88 kVA — built as a soundproof canopy set package for small commercial and light industrial.

A hotel or commercial building cannot be evacuated for a two-hour outage, and guests notice a noisy set immediately. This 70 kW silent set (87 kVA prime, 77 kW standby) is specified for that combination. The load profile is dominated by HVAC, lifts and domestic water, all of which have high starting currents. The 4BTA3.9-G11 engine is matched to the 70 kW rating and the enclosure is lined to keep noise inside it.

Every unit is assembled and load-tested on our own production line for the 70 kW class. The silent build measures 2,920 × 1,100 × 1,890 mm, so the set can be installed at basement level or in a service yard close to occupied areas. Every unit is assembled and load-tested on our production lines. Shanghai Outevo Machinery Co., Ltd. has manufactured diesel and gas generator sets since 2006 from a 20,000 m² manufacturing facility, and more than 2,000 sets have been delivered to over 100 countries.

Protection on the 70 kW set is IP23 or higher, upgradable for dusty, humid, rainy or high-temperature sites.

• ✓70 kW prime / 77 kW standby at 380/220 V, 50 Hz, 1500 rpm
• ✓Full service access — removable canopy panels onto every service point
• ✓Tier-1 diesel engine platforms — Cummins, Perkins, Weichai and Yuchai
• ✓Closed water-cooling with forced fan and large-capacity water tank
• ✓IP23 or higher, upgradable for dust, humidity, rain and heat

Product features

Engineered for site conditions, not for the showroom

Heavy-Duty Silent Construction

The 70 kW package is delivered assembled on its base frame, so installation at basement level or in a service yard is limited to positioning, fuel connection and cabling.

70 kW Prime / 77 kW Standby Duty

Design duty at 70 kW prime and 77 kW standby covers lifts, HVAC and domestic water, which start together when the mains drops and set the sizing case for the alternator.

Tier-1 Diesel Engine Platforms

The engine is drawn from the Cummins, Perkins, Weichai and Yuchai platforms, matched to the alternator and load-tested before shipment.

Closed Water-Cooling with Forced Fan

Closed-circuit water cooling with forced fan and a large water tank holds temperature through an outage when the set is running at high load in a plant room.

Industrial Protection and Environmental Adaptability

Sealed dustproof, waterproof and anti-corrosion treatment to IP23 or higher, with fire-system and BMS interfaces available so the set reports into the building panel.

Flexible Configuration and Fast Deployment

ATS, remote monitoring and quick connectors can be specified so the set starts automatically and the front desk is not the first to notice the supply has failed.

Applications

Where this 70 kW silent diesel generator set is used

1. Lifts and escalators Keeps vertical transport available during an outage, including the motor starting surge of each lift as it re-starts.

2. HVAC and guest-room services Carries chillers, air handling units and room controls so occupied rooms remain usable.

3. Domestic water and boilers Runs booster pumps and boiler controls for hot water, the load guests notice first when it stops.

4. Kitchen, laundry and cold rooms Protects refrigerated stores and keeps kitchen and laundry equipment running through the outage.

5. Lobby, corridor and façade lighting Supplies the lighting levels needed for safe circulation in public areas.

6. Fire, lifts and BMS Backs up fire pumps, lift control and building management systems required for safe occupancy.

FAQ

Frequently asked questions about this 70 kW silent diesel generator set

What power rating does this generator set provide?

This model is rated 70 kW (87 kVA) prime and 77 kW standby, using 4BTA3.9-G11 with a silent canopy of 2,920 × 1,100 × 1,890 mm. Ratings, voltage and frequency are configured to your project specification.

Which diesel engines are available for this set?

For hotels and commercial buildings the silent build is usually specified for noise at the site boundary; open frame, containerized and mobile builds of the same rating are available under OEM/ODM terms.

Open frame, silent or containerized — how do I choose?

Enclosure choice follows the installation point. At 70 kW the silent build suits a basement plant room or service yard close to occupied areas; open frame and mobile builds use the same engine and alternator.

Can the voltage and frequency be customised?

Yes. 380/220 V and 50 Hz are the published standard for the 70 kW rating, and voltage and frequency follow the building specification under OEM/ODM terms.

What is the minimum order quantity?

A single 70 kW unit can be ordered for one property. Where a portfolio or an extension is planned, parallel operation and load sharing are configured from the outset.

How is the quality of each unit assured?

Every 70 kW set is assembled and load-tested on our own production lines and ships with a data sheet and test record. Shanghai Outevo Machinery Co., Ltd. has manufactured generator sets since 2006 with more than 2,000 units delivered to over 100 countries.
