A heatable high pressure cleaning appliance is provided with an undercarriage and a housing lower part, arranged on the undercarriage, in which a motor and a pump driven by the motor for pressurizing water are arranged, and with a fuel-operated heat exchanger for heating the water and a fuel tank for storing liquid fuel for the heat exchanger. In order to further develop the heatable high pressure cleaning appliance in such a way that it has a high mechanical stability and is producible in a cost-effective manner, it is proposed that the fuel tank is configured as a one-piece plastic hollow body, which forms the housing lower part and is held on a rigid support frame, wherein the support frame forms a shock protector that at least partially surrounds the fuel tank in the circumferential direction.

Systems and methods for providing a medical tool cleaning and/or lubrication system are provided. A cleaning system may include an attachment interface configured to receive one or more medical device tool modules. The attachment interface may include one or more input or output couplings which are configured to connect the attachment interface to a reservoir which provides one or more fluids in an input/output pathway for the circulation of the fluids into the one or more medical device tool modules. The cleaning system may also include one or more fluid reservoirs which contain fluid to be circulated through the one or more medical device tool modules. The cleaning system may further comprise a driver system configured to at least partially actuate components of connected medical device tool modules while the modules are being cleaned.

A fluid flow system for a laundry appliance includes a blower that delivers process air along an airflow path having a heat exchanger. A drain channel receives condensate from the heat exchanger and fluid spray from a spray nozzle for directing lint particles to the drain channel and on to a sump for collecting fluid, including the condensate. A pump seat and a fluid outlet are integrally formed in a sump cover. A pump directs the fluid from the sump to the fluid outlet. A fluid level sensor detects at least minimum and maximum capacities of the fluid in the sump. When the fluid is below the minimum capacity, the pump defines an idle state. When the fluid reaches the minimum capacity, the pump defines an active state. When the fluid exceeds the maximum capacity, the pump directs the fluid to the fluid outlet.

The present invention comprises a self-cleaning condensate drain fluid pressure trap for air conditioning. Particulates present in the air which pass through an air conditioner adhere to moister (condensation) which is present on the internal evaporator coil. Condensation drips off the evaporator coil along with the particulates which has mixed in with it. Air-conditioning condensate fluid and particulates, or debris, accumulate inside an air-conditioner evaporator coil drain pan and are drained outward through the condensate fluid drain opening. Condensate fluid pressure traps, necessary accessories of a condensate drain line, are normally secured to the drain pan right outside of the air conditioners drain opening. Since condensate fluid is slow flowing, and not pressurized, debris that drains out of the air conditioner tends to settle in the bottom of the condensate fluid pressure trap. The debris will build up until a clog or restriction to drainage flow occurs. This description of events is based on my experience as an HVAC service technician and from cases gathered from other HVAC professionals.

This device, a self-cleaning condensate drain pressure trap for air conditioning, can prevent air conditioning condensate drain pan fluid overflows due to debris restrictions which occur in the condensate drain fluid pressure trap or elsewhere in the condensate drain line. In preferred embodiments a printed circuit board (PCB) is an incorporated part in the self-cleaning condensate drain pressure trap assembly. The PCB is designed to sense condensate fluid in the sensor cap at the high level of section 1a of the fluid pressure trap. Once the positive presence of fluid is sensed a relay on the PCB breaks the control voltage to the air-conditioners controls or thermostat. The invention then utilizes the incorporated fluid pump to circulate condensate drain fluid from section 1a of the pressure trap into section 1b of the pressure trap in a manner which is perpendicular to the normal fluid drainage flow through the fluid trap. This fluid pumping action loosens debris in section 1b and allows the drain fluid accumulated in the drain pan of the A/C unit to push the debris restriction out of the pressure trap by kinetic gravitational fluid force. After the debris is broken down and pushed through the fluid trap condensate drainage will resume. Unless there is another fluid restriction elsewhere in the drain line. When the PCB senses a negative presence of fluid at the sensor cap air-conditioner operations will be restored. If fluid drainage restrictions persist and a positive fluid presence at the sensor cap continues the PCB will c

A method for stripping a coating off of a blade includes discharging liquid nitrogen through a nozzle onto the blade at a coating to cause lifting of the coating from a substrate of the blade and traversing the nozzle along the blade to cause peeling of the coating off of the substrate of the blade as the nozzle traverses the blade.

A method for automatically cleaning a solar panel using an atmospheric water generator is provided. The method includes the steps of generating water using the atmospheric water generator. The water can be stored for using in a cleaning operation. The system can monitor the efficiency of the solar panel power generation.

The stored water can be pumped through pipes and nozzles to clean the solar panels. The system can automatically initiate the atmospheric water generator to replenish the used water. The system can use a portion of the power generated by the solar panels to perform the cleaning and water generation operations. Accordingly, an automatic and self-contained solar panel cleaning method and system is provided.

A mobile decontamination system has an internal combustion engine, a generator, a first pump, a boiler and a second pump. The engine is coupled to the generator and to the first pump. The first pump is designed for discharging a first decontamination medium via a first spray lance. The second pump is designed for discharging a second decontamination medium via a second spray lance. A system controller is designed for selectively operating the first pump and the heating boiler in one of at least two different operating modes. In the first operating mode, the first pump delivers a first volumetric flow through the boiler which is at such a high level that the first decontamination medium is in liquid form. In a second operating mode, the first pump delivers a second volumetric flow through the boiler which is at such a low level that the first decontamination medium transfers into gaseous form.
