Many appliances and electronic products – ranging from air conditioners to DVD players to TV lifts – cannot be entirely powered down without unplugging them or turning off the power supply at the outlet. These products use small amounts of electricity even when not actively being used. This power consumption is referred to as “standby power.”
Although individual products generally utilise a very small amount of standby power, a typical Australian home often has in excess of 30 different products using standby power at any given time. Over a billing cycle, standby power can account for 5 – 10 percent of a household’s total power consumption. On a global scale, it is believed that standby power is responsible for roughly 1% of worldwide C02 emissions.
There are, however, actions you can take that have a direct impact on your home or business’ standby power consumption. Taking the example of height adjustable desks, this calculator shows you your current standby power consumption and how much it could be reduced by using specialized standby power reduction technology.
– Plug electronic appliance into power strips and turn off the strip when no products are in use.
– Get into the habit of eliminating standby power consumption by unplugging electronic products or turning off the outlet’s power.
– Invest in an inexpensive watt meter, which will allow to measure the standby power consumption of specific products and take targeted action.
Unfortunately, in some situations, it’s simply not feasible to switch off the power to a particular product. In such cases it is wise to look for electronics powered by technology, such as Zero™ technology by Linak that significantly reduces power consumption, greenhouse gases and power bills

Standing desks continue growing in popularity as home and office solutions by promoting healthier work habits through a more active work style. In most cases, the height adjustable systems for standing desks can be driven or assisted into position through electricity, pressurized fluid, or compressed air. In this post, we will be comparing the characteristics found in most hydraulic, pneumatic, and electric standing desks to help you better understand which type will be the best match for your needs.
In general, good quality standing desks offer major health benefits for their users through proper ergonomics and comfort, leading to a long-term positive impact on our mood, productivity, posture, and mental health. The option to stand up can help increase overall work performance and concentration by helping users feel more awake compared to when seated down. With desks and monitors adjusted to the correct height, neck strain and back slumping can be eliminated from our day.

Productivity also improves from having better morale and proper posture when adjusting a workspace to the ideal height position of each user. This is because a comfortable working position reduces the rate of workplace injuries that happen from improper posture. When compared to non-adjustable desks, height adjustable standing desks also offer the added versatility of being able to adjust for the varying heights of different users who may take turns sharing the same workstation.
Electric adjustable standing desks use electric motors to convert electrical power into mechanical force. This mechanical force is then translated to linear motion for moving the motorized legs to the user’s desired position. In our electric standing desk technology, we use brushed DC motors in conjunction with gears to allow for the necessary speed reduction for greater torque and a higher weight capacity.
Control boxes are essentially the brains of our electric stand up desks. They are responsible for reading the positions each leg has traveled to and would then output the necessary amount of power to ensure the legs move to the desired position synchronously. By adjusting how much power is coming from the output, the control box can detect and correct for most disturbances such as uneven weight distribution, aging motors, and physical obstructions. For a control box to determine what positions their electric motors have traveled to, there will be a type of positional feedback involved in the system such as our hall effect sensors.
As the motor of our electric stand up desks rotates, square pulses of 5 Volts are being generated from the hall effect sensors. These pulses will then be counted by our control box to accurately determine the positions that each leg has traveled to. Electronic remote controllers allow users the ability to provide inputs to the control box of their desk, ultimately moving it up and down. By activation of the remote, signals from the remote are sent to the input ports of the control box. The control box determines how much power needs to be supplied to the output ports for the motorized legs to reach the set point(s) which was commanded by the user holding the remote.
Pneumatic standing desks operate in a similar way to our mechanical desk converters that use gas-assisted springs. Compressed gas such as nitrogen flows from one end of the piston to the other through their valve openings.
The completely sealed unit has the same pressure on both sides, however, the pressure acts over a greater surface area from behind the shaft when compared to the front of the shaft’s base. This is because the shaft’s center takes up some surface area from the front side, resulting in a greater amount of force experienced from behind to push the rod out during extensions.
Applying enough weight or force against the shaft will cause the shaft to move further inwards and retract. Compressed gas then goes through the valve opening and will keep getting more compressed until the shaft has fully retracted, or the applied weight is equal to the force exerted by the gas-assisted spring. This compression is happening because the shaft is now occupying space that was previously taken up by the gas. If the weight applied against the shaft becomes less than the force exerted by the gas-assisted spring, the shaft will begin extending once more. Users will usually need to manually adjust the tension settings of their pneumatic sit stand desk using a wrench to account for any changes in weight applied to the top of the workstation.
These gas-assisted springs help reduce the amount of manual effort required by their users to move the workstation to the desired height position. Once the user has chosen their preferred height, a pneumatic sit stand desk will then have a type of lever mechanism for users to lock the gas-assisted springs into place.

Instead of using compressed air, hydraulic standing desks use pressurized fluids inside their hydraulic cylinders to transmit mechanical energy when changing the height positions of a workstation. Since hydraulic fluid does not compress like gases, there is much less power loss within the system. These hydraulic cylinders function similarly to hydraulic floor jacks for lifting cars, capable of high force outputs while in a compact size.
Different models of hydraulic adjustable standing desks will come with either a manual crank or an electric hydraulic pump for propelling the pressurized fluid. The most complex type of hydraulic standing desk will have a combination of hydraulic and electric systems working together to achieve similar smart features found in electric standing desks. Some models may also have the option to switch to a manual crank if a power outage was preventing the normal use of its electric hydraulic pump.
The best type of standing desk for you will depend on your personal preferences, budget constraints, user requirements, and environmental settings. Hydraulic standing desks excel in areas such as industrial factories and heavy-duty manufacturing setups that require the most stability, largest workstation surface area, and highest weight capacity ratings to handle heavy industrial loads. Portability is not crucial for these types of setups since they will rarely need to move locations after being installed. Noisy environments like manufacturing facilities also do not require standing desks with quiet operation, making the noise of electric-controlled hydraulic desks perfectly fine.
