Thanks for great videos 👍 Good video on twin compressor pump down 👍can you do video on inverter scroll refrigeration compressors , please 👍 I only worked on old twin 120 KW Sabroe piston compressors systems Amonia and R22 etc 😑 Thanks for great videos 👍

Maraming salamat po. ❤

thank you

Hi Lecky,thanks a lot please make an introduction video about the Boilers

Thank you

👍👍👍

Present mr. Secretary 😊 about sa plc naman Sec.

Hello sir can you please suggest a book for understanding single line diagram and learn about switch gear and Power systems protection, relay setting and fault current calculation

Thank you sir can you make video for same A.C change over . And can make video on main engine course in simple way.

Hi Lecky, Frst of all thank you for your wonderful easy explanation on each of your video. Im having a trouble on my ushio ref system, which is no 1 compressor is getting frosted if i let the system run. Now i changed over to no:2 not pumping down , but by charging no 2. What may be the probable reasons for the frosting, no fluctuation in suction and discharge pressure. R417A was charged on no:1 last week.

Sir, plz do a video on insulated neutral system in ship 🙏🏻

Leckyjake hello leck could you also make video of procedure of vaccum of the system too weather Aircon or reefer thanku you ver much in advance🙏

Thank you so much sir .. sir I will ask about high pressure. if vegetable ekspnsi V/v open high pressure more up until 1.8 and then direct trip .. iwhat problem sir?

a very good explanation sir. you said that we need to run the compressor two times so if during the first time the low pressure switch activates how can we restart again the compressor or how will the compressor start again? will the pressure increase itself due to remaining refrigerant on the system?

Sir please video on circuit diagram reading

Please give education how to change oil the provision ref machine..thx

Please share how to trace electrical wiring diagrams...for example motor and starters circuit

Next time please add "What not to do" I learn more by learning from others mistakes.

Thanks but why do we need the system to be pumped down? Why we can't keep one compressor off (rather than isolating it)? Thanks.

Sir, When you were pumping down the condenser of unit 1, the unit 1 was running in auto mode ?

So the switch of compressor is off already before the closing the service valve? Am i right?

Good day lec. I have a question I experience during pumping down discharge pressure is increasing until high pressure trip activated and suction pressure is not decreasing hard to activate the low pressure switch. What is the cause? For that reason I cannot properly pump down and changeover to another one compressor. Hope it will answer Thank you in advance.

My dear what is the problem of freezer room start and stop again and again even if refrigrant gas is infe amount in the system

sir. acceptable npoba yung negative 17 s meat storage? gusto kc nila negative 20 medyo naggalangan ako galawin . tnx

Why crack open for suction side valve ??

Hello sir , I’m having a bachelors degree in Electrical and Electronic engineering and I will like to work on board . What are the steps I to go through before getting a seagoing job

Crack open lng ba talaga yan sir yong suction normaly? Or i full open mo rin yan.

Sir asan maganda .mag training sa pilipinas about electrical and reefer dto ako sa US as a Merchant Marine sa APL mahal ang training dto nasa $20k per training ng reefer at electrician and it takes 6 months

Hello sir.. i just ask if you need to deactivate first or set some setting in the control to not activate the pressure switches while doing pump down??? Thank you in advance

Haven't reefer containers made these systems obsolete?

Ano po yung dahilan bakit need munang naka crack open lang ang service valve ng suction side sa compressor 2? Thank you idol 🙂

Sir leckyjake patulong naman yong fish room namin ayaw mag reach sa -18 ,hanggan-13 lang sya. Palaging nakabukas yong expansion valve kaya nag ice na yong evaporator. Kahit nag depros na kami ayaw pa din talaga tumaas . Patulong po. Salamat idol

please can u send this unit diagram

I want to join criuse line i have 5 year experience in Dubai can you help me
