Description

The UMP-400 Universal Motor Pre-heater is a self-contained mobile heating complex built on the Ural 4320-1912-60 all-terrain 6×6 truck chassis. Manufactured by Unisteam Steam Equipment Plant LLC in Miass, Chelyabinsk Region — a specialist in oilfield mobile heating technology — the unit delivers between 175 kW and 400 kW (0.344 Gcal/h) of thermal output, maintained automatically at a supply-air temperature of 110°C.

Two Italian BALTUR burners (220 V each) provide staged combustion on diesel fuel with consumption not exceeding 30 litres per hour, feeding the ВЦ14-46 centrifugal fan that moves 18,000 m³/h at 1,200 RPM and 1,200–1,600 Pa of duct pressure. Heat is distributed through twelve flexible hoses of 220 mm bore and 6,000 mm length via five independent outlets, enabling simultaneous pre-heating of multiple large diesel engines or pieces of equipment from a single unit.

The 350-litre on-board fuel tank provides more than ten hours of autonomous operation. The 40 mm-wall insulated metal-frame van body houses the heating assembly, a 1,500 W inverter, spark arrestor, on-board grounding reel, and fire extinguisher.

The Ural 4320-1912-60 base chassis features a 230 hp Euro-5 V6 diesel engine, a five-speed YaMZ-2361 mechanical gearbox, 6×6 permanent all-wheel drive, and 425/85 R21 all-terrain tyres — delivering full cross-country mobility to remote oilfield sites regardless of season. Climate rating is У per GOST 15150, confirming suitability for Russian continental conditions.

Details & Equipment

Complete Unit

Three-quarter front view

Chassis & Field Readiness

Ural 4320 cab — front view

Head-on view of the Ural 4320 bonneted cab. The 230 hp Euro-5 V6 diesel and permanent 6×6 drivetrain give the unit class-leading mobility across unprepared oilfield roads.

Front-right angle

This angle highlights the side-mounted equipment body and the cab-to-body gap. The Ural's deep-lug 425/85 R21 tyres handle soft ground, snow, and ice without chains.

Features

🔥

400 kW Thermal Output

Two automated BALTUR burners (220 V each) produce up to 400 kW (0.344 Gcal/h) and are adjustable down to 175 kW (0.15 Gcal/h). Supply-air temperature is controlled automatically at up to 110°C.

💨

High-Flow Centrifugal Fan

The ВЦ14-46 fan delivers 18,000 m³/h at 1,200 RPM with a working pressure of 1,200–1,600 Pa, ensuring hot air reaches target equipment through long flexible hoses with minimal heat loss.

🔗

12-Hose Distribution System

Five outlets supply twelve 220 mm-bore flexible hoses each 6,000 mm long, enabling simultaneous pre-heating of multiple vehicles or large-displacement engines from a single deployment.

⛽

10-Hour Fuel Autonomy

The 350-litre on-board diesel tank and a consumption ceiling of 30 L/h guarantee at least ten hours of uninterrupted operation, reducing refuelling stops in remote oilfield locations.

🚛

Ural 4320 6×6 All-Terrain Chassis

A 230 hp Euro-5 V6 diesel, five-speed YaMZ-2361 mechanical gearbox, and 425/85 R21 tyres on a permanent 6×6 drivetrain give the unit reliable mobility on unprepared oilfield access roads and frozen terrain.

🛡️

Integrated Safety System

Standard-fit spark arrestor, fire extinguisher, and on-board grounding reel reduce fire and static-discharge risk; automatic temperature control prevents overheating of connected equipment.

Buyer Benefits

Five simultaneous hot-air outlets and twelve hoses allow parallel pre-heating of an entire vehicle fleet from one unit, cutting crew requirements and time-to-ready
Automatic maintenance of 110°C supply-air temperature eliminates constant manual adjustment during multi-hour heating cycles
350-litre fuel tank provides 10+ hours of autonomous operation per fill, minimising downtime for refuelling in remote locations
6×6 Ural 4320 all-wheel-drive platform handles mud, snow, and frozen terrain on oilfield and construction-site access roads
Euro-5 engine certification satisfies environmental licensing requirements common on modern Russian and export oilfield concessions
Wide factory upgrade menu — GLONASS navigation, extra lighting, winches, additional fuel capacity, cab pre-heaters — supports project-specific customisation direct from Unisteam
Climate code У per GOST 15150 confirms suitability for the full range of Russian continental operating temperatures without special preparation

Applications

Pre-heating wellhead equipment, Christmas trees, and downhole assemblies before winter well operations Cold-start warm-up of drilling rig prime movers and diesel power plants at remote oil and gas sites Simultaneous pre-heating of oilfield service fleets — tankers, pump trucks, and well-service vehicles — before shift start in arctic conditions Pre-heating of heavy earthmoving and mining equipment during winter maintenance periods Heating separator vessels, manifolds, and process pipework to restore flow during cold-season shutdowns Winter engine warm-up for military and emergency-service vehicle convoys in extreme cold regions Field support for pipeline and road-construction machinery operating in Siberia, the Urals, and the Russian Far East Creating heated work zones around outdoor industrial equipment during low-temperature maintenance operations
