As a design and manufacturer of the marine propulsion units, all the products we manufacture are with mature techniques,we have a professional technical team with decades of experience in the design/Prodction/quality control and the after-sale service.Â
 We are mainly woring with state and governmental projects, shipyards in china, CSSC,CSIS, design Institute, shipping owners, clients from European and East-south Asia. We have continuous collaboration with national & private ship design institutes as well.
  Since the fountation of SJMATEK in 2013, we have supplied more than 200 vessels with our tunnel thruster/rudder propeller and CPP, All of them are working well !  all the products can men produed according to the requirements and provide the certificate accordingly, presently , we can offer the certificate like CCS ,ABS ,BV ,LR ,DNV .RS etcÂ
 There are 2 types of rudder propeller: Fixed Pitch Tunnel Thruster and Controllable
Pitch Tunnel Thruster which are used for the Large tugboat, harbor tug, drilling platform vessel, ocean engineering vessel etc, it has advanatges as follow:
1/ Rudder and thruster in one. Rudder propeller can steer in any direction of 360°above the water level.   Provide all-around thrust.
2/  Three installation: deck/ transom/Well  Â
3/ The power can be supply by e-motor or Prime moverÂ
Presently the propeller dia. we can do from 250mm to 3300mm, input power from 20KW to 3500KW.

The spotlight is the use of concentrated lens or mirror to light.Reflected light spot light type is simpler, intensity of illumination is strong, according to the picture of narrow, facilitate the scene in the specific geographical focus light lamp, indoor studio and studio with at most a lamp.LED spot light adopts LED as light source.
The difference is led spot light and spot light, led spot light is the led lamp bead, rather than the traditional light bulb, the service life of led lamp bead long service life than traditional light bulbs, function is the same, are concentrated.
LEDs are produced by superconducting luminous crystal ultra high strength light, it emits less heat and, unlike incandescent light gives off a lot of heat, not because of high energy consumption and produce toxic gases like fluorescent lamp, also don't like neon lights for high voltage and easy to damage, has been all is recognized as a new generation of environmental protection high-tech products.
