Hoyer Explosion proof marine motors 0,37 to 347 kW

Description

The HMCX explosion proof marine motors are characterised by high material quality and a proven robust design. They are designed according to international standards in conformity with below.

GB – 3836.1, 3836.2, 3836.3
IEC – 60079-0, 60079-1 and 60079-7
EN – 60079-0, 60079-1 and 60079-7/A1

The motors are low voltage three-phase TEFC motors, and designed in protection enclosure „db“. They can be used in zone 1 explosive atmospheres, group of use IIB/IIC covering all industries except mining. In these areas an explosive atmosphere can occur during normal operation (zone 1). Dangerous zones in the marine and oil & gas industries occurs on many vessel and platform types including gas carriers, semi-subs, tankers, FPSO’s, FSO’s, FLNG’s, FSRU’s etc.
HMCX motors are with cast iron housing, premium quality bearings and provided with ATEX and IECEx certified blind plugs. Motors frame size 80-250 are with closed bearings greased for life while frame size 280-400 comes with regreasable open bearings. All motor sizes have tropical insulation and are equipped with winding heater and 3xPTC. All standard motors have C3L coating according to ISO 12944-5:2018 in color RAL 9005 low gloss.
The range is designed to offer flexible product solutions according to customer and application demands. A variety of options are available including Exe protection, larger size motors, special bearings, higher IP class and various measuring systems.

By open deck applications the motors are often directly exposed to the harsh marine environment. A unique HMCX design is developed to meet the tough demands of open deck operation. It is characterised by a special terminal box and rain cover design including IP 66 protection with the option for IP67 in standstill condition. The open deck motors are especially suitable for below applications which are often installed on LNG/LPG Carriers and Product/Chemical Tankers.
